MZS-NPE400
The MZS-NPE400 is a surge protective device (SPD) designed specifically for connection between neutral and earth (N-PE) in 400 V AC low voltage power circuits.
The MZS-NPE400 is a surge protective device (SPD) designed specifically for connection between neutral and earth (N-PE) in 400 V AC low voltage power circuits. Compliant with IEC Class I/II, IEC 61643-1/IEC 62305-4 and RoHS, it withstands an impulse discharge current of up to 75 kA (10/350 µs) with a voltage protection level of 1.8 kV or less and a maximum continuous operating voltage of 500 V. Its 35 mm DIN rail design allows quick installation in switchboards, distribution boards and control equipment power supply circuits, and it is intended to be paired with the MZS-400AV for a complete protection scheme.
