Series RE - Electronic overload relay
Electronic overload relays have been designed primarily to protect electric motors and associated electrical circuits.
These devices operate on the principle of monitoring the current in a motor starter circuit which, when the current exceeds a pre set condition, or there is a loss of current in any phase, the device will initiate a trip circuit which in turn causes the power to the starter (contactor) to be disconnected thus making the circuit safe.
