Product Description

DCL DUCR Electronic DC Current Relay

Our offered DCL DUCR is a kind of Electronic Current Relay that works on direct current that possess a broad protection range that varies from 1 Ampere to hundreds of Amperes. It owes its implementation in the DC motors by switching contact in the case of overload conditions.

Features

DC Overcurrent 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 Underload protection relays.

  • It has wide DC current protection range from1A to hundreds Amps.
  • DC Ammeter maybe used instead of Shunt (DC Ammeter has its own shunt inside and keep 50mV maintained.)
