ESP200 Solid State Electronic Overload Relays

Across-Line Motor Starters

The field selectable Trip Class 5, 10, 20 or 30 can easily be set by 2 DIP switches. This eliminates the guess factor of application requirements and provides reduced inventory for multiple applications.

ESP200 has a 4:1 current adjustment range with a fine adjustment dial labelled in full load amps. The heater-less overload minimizes the heat trapped in the enclosures, reduces cost for ventilation or cooling. Easily accessible reset button provides visible and audible indications to ensure the tripped overload is ready to restart.

ESP200 can be directly coupled to the contactors or remotely mounted. In addition to the NEMA contactor applications, it also can be used with other types of controllers for applications requiring DP or IEC contactors.
