Decontactors are a combination plug, receptacle and disconnect switch in the same device. Using Meltric Decontactorsto connect motors and other electrical equipment instead of hard-wiring can dramatically reduce equipment change-outrelated downtime. Due to their switch ratings, Decontactors allow users to safely and easily make and break electricalconnections under full load, even in wet, and highly corrosive conditions. This eliminates the need for expensive interlocksand auxiliary disconnect switches. Meltric Decontactors improve safety while saving users both time and money.

Decontactors are built to withstand the harsh environments often found in the food industry. For example, Meltric’ssilver-nickel contacts, stainless steel components, and chemical resistant housings help withstand corrosion causedby frequent washdowns with caustic cleaners. The butt-style pressure contacts ensure excellent electrical connectionseven in dusty or greasy environments. Other features, such as lockout tagout capability and optional integral pilotcontacts, help make the operation of food and beverage plants safer and more efficient.

Overhead connections along a Connecting portable and stationary Modular conveyorproduction line - dairy industry equipment - meat processing connections - pickle line
Reduce DowntimeDecontactors reduce downtime related to electrical equipment change-outs.When Decontactors are used in lieu of hard-wiring, a mechanic can change outa motor safely and efficiently. A conveyor line or a process pump can be upand running in a matter of minutes instead of a matter of hours. Productionhalts are minimized and rewiring errors are virtually eliminated.
Ensure Safety for Maintenance PersonnelDecontactor safety features include: dead front construction, enclosed arcchambers, silver-nickel butt-style pressure contacts, and short circuit make andwithstand ratings ≥ 65kA. These features ensure safety by preventing access to liveparts, by providing a superior electrical connection that does not deteriorate with wear or oxidation,and by allowing users to safely make & break connections - even during wet or overload conditions.
Provide Watertight, Durable ConnectionsDecontactors provide safe, durable electrical connections - even in washdownenvironments. Rated watertightness up to NEMA 4X is achieved as soon asthe plug mates with the receptacle (DS & DSN models). A Decontactor’scoil spring-loaded silver-nickel contacts offer superior electrical performancethat does not deteriorate with wear or oxidation, unlike competitors’ brasspin & sleeve contacts.
Simplify Code ComplianceDecontactors provide food and beverage factories with a simple and cost-effective .means of achieving code compliance. A Decontactor’s switch rating allows it toperform as the NEC required ‘line of sight’ disconnect - the need and expense of
a separate disconnect switch is eliminated. Decontactors also help facil-ities comply to NFPA 70E or CSA Z462 requirements. A Decontactor’s
dead front construction prevents worker exposure to live parts. As a result,qualified mechanics can change out a motor without needing cumbersome PPE.
Allow Easy Production Line ReconfigurationsDecontactors allow conveyor motors and other electrical equipment to be safely
. connected or disconnected with plug and play simplicity. Reconfigurations.......... of production lines are simplified when Decontactors are used to create a. modular system. Time spent performing electrical work is minimized.
Facilitate Quick Disconnection & ReconnectionDecontactors allow easy disconnection, even by operators with gloves on.
. Simply press the latch to break the load and, if desired, lightly twist the plug
. to remove it. Alternatively, the plug can remain in the receptacle to keep itconveniently out of the way. By contrast, pin and sleeve or twist type connections
. require much greater force to remove the plug and once the plug is removed. it often must be laid down on the floor, creating unnecessary clutter.

Spring loading ensures optimal contact forceover thousands of operations. Plus, the per-formance of silver-nickel is not affected byoxidation. By contrast, the contact force ofcompetitive pin & sleeve devices decreaseswith use and the conductivity of their brasscontacts degrades significantly due to oxidation.
Rated watertightness, up to NEMA 4X, isachieved as soon as the plug mates with thereceptacle (DS & DSN). Competitive productsrequire the user to remember to carefullytighten an additional plastic ring.
The dead front design eliminates access tolive parts. They can only be accessed by thecorrect mating plug after insertion into thereceptacles. Meltric’s dead front design alsohelps avoid the need for cumbersomePersonal Protective Equipment and thusallows faster and safer motor change-outs.

Articles 430.101 through 430.113 regulate motor disconnection means.They require motors to have readily accessible, Line of Sight disconnectsthat are either an approved switch or a properly rated plug and receptacle.
� 430.102 A disconnecting means must be located in sight from themotor and driven equipment.
� 430.107 The disconnecting means must be readily accessible.
� 430.109 The disconnecting means must be an approved switch ora horsepower rated plug & receptacle with ratings at leastequivalent to the motor ratings.
� 430.110 The disconnecting means must have an amp rating atleast 115% of the full-load current rating of the motor.The horsepower rating of the disconnecting means mustbe determined based on the sum of all resistive currentsand the locked rotor current of the motor.
This OSHA consensus standard covers electrical safety related workpractices and procedures for employees who work on or near exposedenergized electrical conductors or circuit parts. Relevant requirements include:
Power must be proven to be off before performing work. This includes:
� The safe interruption of the load & opening of the disconnect
� Visual verification/voltage testing to ensure deenergization
The potential electrical hazard must be identified and documented.
� Flash hazard analysis must be performed
� Flash protection boundaries must be determined
Appropriate steps must be taken to protect persons working near liveparts or within the flash protection boundary.
� Personal Protective Equipment must be provided based on therelevant incident energy exposure levels (cal /cm2)

Use auxiliary/pilot contacts for oper-ating secondary control circuits or forelectrical interlocking with the motorstarter. These contacts make last andbreak first when the plug is engagedor disengaged. Two to six auxiliarycontacts are available on a Decontactor.
An emergency stop pawl is availableas an alternative to the standard pawl.It provides a larger button that iseasier to actuate, making it ideal inareas where quick disconnects maybe required.
Use padlock pawls or padlock plug capsfor preventing unwanted connection ordisconnection of plugs. Padlock pawlsalso allow the lid to be locked closed.Padlockable plug caps provide NEMA4X watertightness (DSN only).
Normally closed lids for femaledevices are available for applicationswhere the receptacle will be exposedto excessive moisture or debris.The lid will automatically close toa pre-latch position.
Use PH or PM handles for connectingto flexible conduit, for strain relief onsuspended connections, and forenhanced watertightness. Finger drawplates should also be considered foreasier connector closure.
Nylon conduit entry boxes are availablefor washdown applications where ametallic box is not desirable. Applicationsutilizing large wire sizes should bechecked for ‘fit’ before ordering.

Closed Lid Configuration
Self-Ejecting Devices
Meltric’s self-ejecting system employs a “fin” type pawl, which is activated by a tension cord attached between the pawland the power cable. Tension on the cable pulls the cord, releasing the pawl and uncoupling the device. Self-ejectingmodels connect with straight insertion to permit automatic ejection. This option is ideal for truck hook-ups, fork lifts,and refrigerated or heated food carts.
A tension cord is
attached to the
power cable and the
fin pawl of the plug.
Tension on the power
cable automatically
lifts the fin pawl via
the tension cord.
Once the pawl
is lifted, the plug
pulls away from
the receptacle.
