EOCR - SP40 Electronic Overload Relay

Offered Electronic Over Current Relay EOCR - SP40 is mainly employed for assessing functions for excessively prolong starting time on rigs with a danger of troublesome starting, In addition, this relay can be deployed for quicker identification of malfunctioning on machinery where the engine is excessively sized in compare to the thermal protection.

Model No: EOCR - SP40

Features
  • 3 integral current transformers
  • Electronic shear-pin function
  • Independently adjustable starting rip delay (D-time) and Trip time (O-time)
  • Fits directly in to IEC or NEMA contractor
