Maximal current relay RMT-101

Country of origin: Россия

RMT-101 current overload relay is used for load rejection in case the current exceeds the set value between 0 and 100 amperes.

The device can be used in the following capacities:

LEDs on the front panel of the relay indicate:

Depending on the work mode, the three-digit seven-segment indicator indicates:

Regulating potentiometers allow the user to set the following values:

maximum allowed load current value threshold;
time for load rejection in case of exceeding;
maximum allowed load current threshold;
time delay before load activation after the current returns to the allowed level.
