Direct Current Overcurrent Relay for DC Motor and Machineries. ■ The milIi-volt (mV) signals generated from the Shunt 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 Underload protection relays. ■ It has wide DC current protection range from 1A to hundred Amps. ■ DC Current Meter maybe used unstead of Shunt. (DC Current Meter has its own shunt inside and keep 50mV maintained.)
