Application

ZMB series harmonic current protector is used in the system of AC50/60Hz, nominal voltage 0.4KV or 0.5KV, series connected with capacitor, to restrict the surge of switching capacitor bank, reduce the interference of harmonic current to capacitors, and eliminate the reinforcement of capacitor discharging current when the system has short circuit fault.

ZMB series harmonic current protector enclosed by epoxy resin, good figure, easy to install, high insulation level and anti damp, protect inner components from access of moisture and weather.
