The three-phase overcurrent protection PZ-35T is used in protection and signaling circuits to detect deviations of the measured alternating current above or below the set value. PZ-35T is a three-phase protection with a homopolar element, instantaneous action and time delay of operation with independent time characteristics. DC or AC auxiliary voltage is required for the auxiliary power supply of these protections (or the power supply is from the measured value, if so required).
