Meltric Benefits

Quick Equipment Change-outs

The quick, safe and flexible connection capabilities of Meltric Decontactor™ Series plugs and receptacles makes them the ideal choice for plug and play and modular process applications. Modular factories commonly use Meltric to connect to electrical drops for quick connection/disconnection and rearrangement capabilities with total safety.  Using Meltric Decontactor Series Motor Plugs to connect motors and other equipment instead of hard-wiring can help reduce equipment change-out and downtime costs by as much as 50%. Pre-wiring replacement motors with Meltric plugs eliminates the time, cost and hassles of needing an electrician to do wiring during change-outs and perform associated safety related work practices. Most importantly, you get your process back on-line in a fraction of the time.

Improper phasing can easily be corrected by switching wire locations on the receptacle. Test receptacles with matching poplarization should also be installed at the motor service shop. This allows the electrician to verify that the intended direction of rotation has been achieved each time a plug or inlet is wired to a motor. Mechanics can safely connect motors that are pre-wired in this manner simply by plugging them in. The correct motor operation is ensured and the problems and additional downtime resulting from improper rotation is eliminated.
