Our offered DUCRA DC Undercurrent Relay is highly demanded for fulfilling the engineering applications that require the need of monitoring the current. It basically monitors the flow of undercurrent using the separate settings and other outputs supported for such current flows. The mentioned relay also allows automatic or manual resetting of the operations.

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.)
