Compact single-phase surge protector
Common / differential protection modes
Operating / disconnection indicators

The surge protection function is pluggable to make maintenance simple and rapid if there is a disconnection, indicated by the red light indictor. The technology is based on varistors equipped with thermal disconnectors and operating-failure indicators.Discharge currents: In: 3kA / Imax: 10kA
