The MZAC-200 is a compact IEC Class III surge protective device (SPD) designed for the secondary side of a leakage breaker in single-phase two-wire systems. Compliant with IEC 61643-11 and RoHS, it offers an open circuit voltage of 6 kV (1.2/50 µs), a voltage protection level of 1.5 kV or less and a maximum continuous operating voltage of 275 V AC. It includes a deterioration indicator and a built-in isolation function that prevents overheating if the device degrades. Its space-saving design makes it ideal for installation inside equipment and panels.
