Meltric Sales | Equipment Change-Out


   
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.

Solving the Motor Rotation Issue
 
PROBLEM: INCORRECT MOTOR ROTATION
 
Phase variations within a manufacturing plant and wiring errors during motor installation can cause motors to rotate in the wrong direction, extending downtime and potentially damaging products and/or equipment.
 
SOLUTION: USE DECONTACTOR SERIES SWITCH RATED PLUGS & RECEPTACLES TO HELP ENSURE CORRECT MOTOR ROTATION
     
DECONTACTOR RECEPTACLE
PREWIRED MOTOR
CONNECTING A MOTOR
     
When Decontactor receptaces are installed, a test motor or motor rotation meter can be used to verify that the intended polarization is achieved.
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.
