Overload relay

Overload relays protect a motor from burning out by watching its current and cutting the contactor coil when the draw stays too high for too long, tripping on sustained overload rather than on a short circuit. Panel builders size one when full-load current has to be matched by its protection, when a relay keeps tripping because it was set for a different motor, or when a rewound motor needs its overload reset.

 

As an authorized electrical distributor for multiple manufacturers, we stock overload relays from Schneider Electric, ABB and more across competing lines, in a range of current ranges, coil voltages and contact forms, so you can match the trip class and current the motor requires, compare ranges and coil voltages across brands, and mount a relay to the contactor it has to protect.
