4 Pole AC SPD

CNKA 4 pole ac spd Introduction

Wholesale 4-pole AC SPD CE from CNKA, a China factory, is designed for AC power supply systems operating at 50/60 Hz and 380 V, adhering to IEC standards. This device can be mounted on a 35mm guide rail. Featuring temperature-controlled circuit technology, the 4-pole AC SPD can be integrated with F, making it suitable for low-voltage BCD lightning protection installations in buildings. Typically, it should be placed in low-voltage lightning protection device floors, distribution box counters, central telecommunications rooms, elevator control rooms, variable control rooms, and distribution boxes housing electronic medical equipment.
