Your problem: Today, you need a time-delay power fuse that can handle normal surges. Tomorrow, it’s a power fuse with a high interrupting rating and the added security of rejection dimen-sions. The day after that, one of those economical one-time power fuses will do the trick. But where can you turn for all three?

Our solution: Ferraz Shawmut’s comprehensive power fuse offering covers a complete range of applications and a complete range of circuit-protection needs. Whether it’s the characteristics of our Tri-onic® time-delay fuses. The high current-limiting capacity of our original Amp-trap® power fuses. The cost-efficient protec-tion of our One-Time fuses. Or some other application-specific power fuse solution.

Want more information fast? For more technical or application-specific information, please call our Power Fuse experts, at 978-462-6662; 416-252-9371 in Canada; or visit our website at us.ferrazshawmut.com.

The new High Speed J (HSJ) combines the low I2t of a semiconductor fuse and the branch circuit performance of a Class J UL listed fuse. This fuse was designed for the starting characteristics of solid state motor controllers. The HSJ can provide branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCR’s, GTO’s and SSR’s.

When it comes to protecting service entrance equipment, feeder circuits, and circuit breakers, A4BY fuses have been the industry’s favorite. The A4BY is a 100% rated device and may be applied at continuous currents up to its ampere rating. A 4-second minimum time delay at 500% rating allows the A4BY to pass normal current surges and to coordinate with ground fault relays.

The high interrupting rating of A4BT current limiting fuses is ideally suited for protecting mains, feeders, and general circuits. The 10-sec-ond time delay at 500% of fuse rating is ideal for large motors and other loads with a high inrush. A4BT fuses are suitable for DC applications up to 500VDC. An A4BT fuse can be applied to normal loads up to its full ampere rating to allow 100% rating of equipment.

HiGH speeD RK1 (HsRK)

Protect your electrical power wiring and power semi-conductors with a single fuse.

The new HIGH SPEED RK1 (HSRK) combines semi-conductor fuse performance with NEC branch circuit compliance. The fuse was designed with two specific applications in mind: 1. To provide semiconductor fuse performance

to solid state drive applications but in the larger RK body sizes that have been typically installed in older systems.

2. To provide industrial power applications with the most current limiting fuse available, which in turn provides the best arc flash mitigation available to power systems using the larger RK size fuses.

small Fuse - BiG pROTeCTiONFOR GeNeRal CiRCuiTs

Amp-trap® ATMR fuses, in the Class CC family, are the smallest dimension 600VAC/DC fuses suitable for branch circuit protection. The ATMR is a popular choice for economical protection of control circuits and control circuit transformers where available short cir-cuit currents exceed 10,000 amperes. ATMR’s rejec-tion dimensions prevent substitution by lesser rated fuses. These fast acting fuses give current limiting protection to general circuits.

FOR versatility and economy, THeseGeNeRal puRpOse Fuses aRe HaRD TO BeaT

OT, OTN and OTS general purpose fuses provide low cost protection for feeder and branch circuitsserving lighting, heating, and other non-motor loads. OT, OTN and OTS fuses will safely interruptavailable short circuit currents up to 50,000 amperes in all ratings.

OT, OTN and OTS fuses are not rejection fuses – care should be taken to ensure that replacement fuses do not have lower interrupting ratings than original fuses.

OTN 15 through 60 satisfy the Canadian electrical code requirement for Type “P,” low melting-point, non-time delay fuses.


CSA Certified to Standard C22.2 No. 248.9*

Ferraz Shawmut Certified for DC per UL248

*The Canadian ElectricalCode requires these fuses in ratings 15 through 60A to be of the low melting point design use OTN 15-60.
