ESP200 Solid State Electronic Overload Relays

  • Selectable Trip Classes: 5, 10, 20 and 30
  • Manual, automatic, and remote reset
  • Phase loss protection - trips in less than 3 seconds
  • Phase unbalance protection - trips based on trip class selected (minimize temperature rise of the motor on a asymmetrical three-phase system)
  • Thermal memory (prevents restarting the motor when it is hot)
  • Ground fault protection - trips 60% of motor current
  • Ambient insensitive (prevents nuisance tripping)
  • FLA dial with wide adjustment range - 4:1 ratio
  • One NO and one NC contacts standard
  • Self-powered - no separate source required
  • Self protected in short circuit condition
  • No heaters required (saves cost and eliminates time for installation)
  • Test button - tests electronics
  • Conformally coated circuit board
  • Repeat trip accuracy <1%
  • Visible trip indicator
  • DIN Rail Mounted
  • Touch-safe terminals
  • Removable terminals

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.
