Overload Relays

Motor failures are expensive. There's the cost of replacing or repairing a motor and there's also the cost of downtime when your system is sitting idle. The good news is that electric motor protection isn't expensive or hard to configure.

Because electric motors commonly pull up to 6X the nameplate amp rating at startup, fuses and circuit breakers aren't the recommended protection device. Overload relays are the proper motor protection device for electric motors.

The Siemens ESP200 Solid State Overload Relays are configured simply by matching the FLA dial to the FLA rating of your motor and selecting the proper trip class for your application. They have ground fault detection, phase loss protection, phase unbalance protection, thermal memory to prevent restarting your motor while it's still too hot, and they even protect against short circuits.

Electric motor protection made easy.
