General Description

Facility-Wide Protection

A Facility-Wide Protection Strategy Should be Employed to Address Power Quality Issues

Why Coordinated (Cascaded) Facility-Wide Protection?As recommended in the IEEET Emerald Book, a cascaded or staged protection approach should be developed and executed to reduce external/internal impulse waveforms to harmless levels. Eaton surge protection solutions are available in all common voltages and configurations, in surge current capacity ratings up to 800 kA and with a variety of optional features such as EMI/FFI filtering, audible alarm, Form C contacts, surge counters and Power Xpert feature package. Eaton’s complete offering of surge protective devices ensures there is a solution for any application in a cascaded facility-wide protection strategy.

A surge device equipped with filtering should be installed at the main service entrance and key distribution or branch panelboards to eliminate ringing and impulse disturbances, as well as high frequency EMI/RFI noise. Filtering is available on the SPD and RSPF Series models.

Eaton surge devices are coordinated to work on a “system basis”. Surge units installed at each level in the system work together to isolate and remove externally/internally generated disturbances, creating superior facilitywide performance and reliability.

Integrated SPD Series units maximize flexibility, space and protection and are available in switchboards, switchgear, panelboards, motor control centers and automatic transfer switches. Integrating the surge device into the electrical assembly maximizes protection by keeping installation leads as short as possible.

Benefits of Facility-Wide Surge Protection■ High amplitude lightning impulses reduced to negligible levels

■ The electrical distribution’s noise attenuation is significantly enhanced

The coordinated design ensures effective current sharing between main and branch surge devices. Installing appropriately rated surge protection at locations throughout a facility provides a layered defense solution and helps ensure complete protection of critical equipment.

General Description

Integrated Surge Protection

SPD Series Unit Integrated Within an Eaton Pow-R-Line 1a Panelboard

Eaton was the first to introduce the “Direct-On™ bus bar” connect SPD that provides customers with the lowest system let-through voltage at the bus bar when compared to traditional cable connected surge protectors.

By using a direct bus bar connection, the SPD Series achieves the industry’s lowest let-through voltage—effectively suppressing both high and low energy transient events providing protection for all connected electronic loads. This design provides superior suppression ratings and eliminates poor performance that results from cable connections and/or long lead lengths.

Other ProductsOther surge suppressor manufacturers’ measurements are made at the SPD module or the suppressor’s terminals, not at the electrical distribution equipment’s bus bar. The distance between module or suppressor terminals and the distribution equipment bus bar is often 14.00 inches (355.6 mm) or more. The impedance associated with cabling required to connect the surge suppressor to the electrical distribution equipment (also referred to as lead length) significantly effects the overall performance of the surge suppressor and results in an increase in let-through voltage.

Figure 34.1-3. 120 V/208 Y Panelboard—Integrated SPD vs. Cable Connected

In this installation, the SPD Series is mounted directly to the panelboard’s bus bars. This type of installation will

provide the best possible surge protection by minimizing the connected lead length.

The SPD Series is also available as an integrated unit interfaced via a circuit

breaker resident in the electrical assembly. This installation keeps connected lead lengths short while providing a means

of disconnecting power to the unit quickly and easily.

Integrated Panelboard SPD

Integrated SPD Series Unit in PRL1a Panel (Shown with Option SPD Integral Disconnect)

Integral disconnect option shown above —for PRL1a, 2a, 3a, and 3E panelboards.

For applications where load interruptions are intolerable, an internal dedicated SPD circuit breaker disconnect option is available. SPD is cable connected via a three-pole 30 A circuit breaker. (Breaker rating and type dependent on panel type.)

Direct Bus Mounted SPD Series Unit in a PRL1a Panel

Another distinct advantage that Eaton integrated SPDs offer is the availability of neutral and ground connections on both sides of the unit. This enables both the neutral and ground wires to be kept as short as possible. Only one neutral and ground connection is required, with the connection point chosen for each being the one that is in closest proximity to the neutral and ground bars.

The presence of neutral and ground connections on both sides of an integrated unit keeps both leads as short as possible, increasing the installed performance of the unit.

Retrofit Surge Protective FD Frame (RSPF) Series

FD Frame

IntroductionEaton’s retrofit surge protective (RSP) series consists of ULT 1449 4th Edition-listed surge protective devices (SPD) that provide a reliable, cost-effective, aftermarket solution for surge protection. Designed for easy installation, this Type 1 or Type 2 SPD is approved for field installation and is capable of easy installation directly into a panelboard or switchboard without any modifications. The RSPF is available in multiple configurations that are specifically designed for Eaton panelboards and switchboards, allowing for installation on systems utilizing most common voltages. Easy mounting options coupled with a compact footprint enable quick installation of the RSPF in panelboards and switchboards in less than 10 minutes.

ApplicationsThe Eaton RSPF series SPD protects critical electrical and electronic equipment from damage caused by voltage transients and surges when properly installed. This is done by shunting high-energy lightning surges (and other transient disturbances) away from the equipment being protected. It does this in nanoseconds by providing a low impedance surge path to ground through thermally protected metal oxide varistors while supporting power frequency voltage.

The Eaton RSPF series SPD was designed solely for aftermarket applications and developed to fit in the space of an Eaton FD-frame molded case circuit breaker. The RSPF is intended for retrofit into existing panelboards or switchboards with space or provisions for the FD frame size.

Features■ Voltage ratings from 208 Vac to 600 Vac■ Uses thermally-protected metal oxide varistor (MOV) technology

■ LED protection status indicators■ 20 kA nominal discharge current (In) rating (maximum rating in the UL 1449 4th Edition standard)

Surge Protection (SPD) products—Integrated ApplicationsApplication Data

EATON www.eaton.com

Integrated SPD Series Voltage Protection Ratings (VPR)The measured limiting voltage test in UL 1449 4th Edition uses a 6 kV/3 kA combination wave surge to determine the voltage protection rating (VPR) of the SPD. This test is similar to the suppressed voltage rating (SVR) as performed in UL 1449 2nd Edition. The key difference between the tests in the 2nd Edition and the 4th Edition is that the magnitude of the current used for the test is six times greater in the 4th Edition versus the 2nd Edition. This much higher current level will mean that the measured limiting voltage will likely be significantly higher for the higher current level. For example, the VPR for an SPD will likely be much higher than the SVR of an identical SPD. With higher current levels come higher limiting voltages. Please note that VPR ratings fall into predefined voltage categories as outlined in the UL 1449 4th Edition. The standard VPR voltages are shown in the following table.

Therefore, if an SPD is tested with a 6 kV/3 kA combination wave surge and the let-through voltage is measured to be 610 V, the SPD is given a VPR of 700 V. The SPD is given the same 700 V VPR if the same test results in a let-through voltage measurement of 698 V. Additionally, if the let-through voltage is measured to be 2005 V, the SPD is given a VPR of 2500 V.

It is important that users are familiar with the difference in testing methods and the subsequent effect on the value of the VPR. Without considering or understanding the differences in the level of currents used in the test, one might assume that a UL 1449 4th Edition device with a VPR of 700 V has a higher limiting voltage than a UL 1449 2nd Edition device with an SVR of 400 V. Such a conclusion would be inaccurate.

The higher VPR rating of 700 V is likely caused by the higher level of surge current during the measured limiting voltage test. In order to make an accurate assessment of devices, the VPR rating of one device must be compared with the VPR rating of another device. Comparing a VPR rating to an SVR rating yields no useful or conclusive information.
