Meltric Decontactors are a combination plug & receptacle and disconnect switch in the same device. With their UL and CSA switch ratings, Decontactors provide users with a cost effective and convenient means of providing the NEC required 'line of sight' disconnect. They also help to significantly reduce motor change-out downtime by combining plug and play simplicity with the safety of a dead-front switch. Motors that are pre-wired with a plug or inlet can be connected simply by being plugged in, and because there is no access to live parts, the need for NFPA 70E required arc-flash hazard analysis and associated PPE is eliminated.

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.
