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.) |
