The current relays MK 9063N and MH 9063 of the varimeter family provide
a solution for an optimised monitoring of the function or the load current
of an electrical device. Single-phase AC and also DC can be measured,
undercurrent, overcurrent and current window are monitored and the
measured value is displayed on the front.
