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.
Code and implication?

?
The performance parameters
The product complies with JB/T9644 standard ?Temperature rise not more than 70K
It can withstand the combined impact of surging current at the maxi capacity of capacitor banks that the protector matches, without electric flashover and mechanical damage.
The reactor can carry the combined current (RMS) of basic current and harmonic current not exceeding 1.3 times of rated current continuously.
