MZS-400AV

The MZS-400AV is a surge protective device (SPD) for low voltage power circuits up to 400 V AC, connected between phase and neutral and complemented by the MZS-NPE400 between neutral and earth. Compliant with IEC Class I/II, IEC 61643-1/IEC 62305-4 and RoHS, it handles an impulse discharge current of up to 25 kA (10/350 µs) with a voltage protection level of 2.5 kV or less. It features high follow current shutoff capability and a deterioration indicator with a warning contact output for proactive maintenance. Its 35 mm DIN rail design makes installation easy in switchboards, distribution boards and control equipment power supply circuits.
