The mentioned DLC DC Overcurrent Relay finds usage in the motor and machinery parts that work on direct current. This product has been engineered using top quality material to ensure that the best performance is rendered for fulfilling the clients' requirement. It possesses shunt sensor that helps in the generation of milli volt signals to be compared with preset overload setting.

Product Type: DC Relay

Features

  • DC Over current Relay for DC Motor
  • The milli-volt(mV) signals generated from the Shunt and power supply are sensed by solid state circuitry and compared with preset overload setting. In case sensing overload condition, the internal relay switches contact after the preset delay. It has easier control operation. It has DC Overload and DC Under load protection relays.
  • It has wide DC current protection range from 1Ato hundreds Amps.
  • DC Ammeter maybe used instead of Shunt (DC Ammeter has its own shunt inside and keep 5omV maintained.)
