MZS-NPE
The MZS-NPE is a surge protective device (SPD) designed specifically for connection between neutral and earth (N-PE) in low voltage power circuits.
The MZS-NPE is a surge protective device (SPD) designed specifically for connection between neutral and earth (N-PE) in low voltage power circuits. Compliant with IEC 61643-11 (Class I/II) and RoHS, it withstands an impulse discharge current of up to 75 kA (10/350 µs) with a voltage protection level of 1.5 kV or less, offering robust protection against direct lightning strikes. Its 35 mm DIN rail design allows quick installation in switchboards, distribution boards and control equipment power supply circuits (AC 100 V/200 V), and it works as a complement to the MZS-200AV for a complete protection scheme.
