Our offered DUC Relay offers selectable de-energized or energized operations that can be helpful for storing last tripped alarm value in the memory. A thorough research is conducted before engineering the mentioned relay for ensuring that only quality is delivered at the clients' end. Apart from this, we use high quality material for its production to render durability and reliability.

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 1A to hundreds Amps.
  • DC Ammeter maybe used instead of Shunt (DC Ammeter has its own shunt inside and keep 50m V maintained.)
