\nType:<\/strong> Earth Leakage Circuit Breaker (ELCB) \/ Molded Case Circuit Breaker with Earth Leakage Protection
\nSeries:<\/strong> WS-V \/ NV-C (Economy Class)
\nRated Current (In):<\/strong> 30A
\nNumber of Poles:<\/strong> 3\u2011pole (3P)
\nRated Sensitivity Current:<\/strong> 30mA
\nBreaking Capacity (Icu @ 400V AC):<\/strong> 5kA
\nApplication:<\/strong> Earth leakage, overload, and short-circuit protection in distribution boards and machinery<\/p>\n

The Mitsubishi Electric NV63-CV 3P 30A is a compact earth leakage circuit breaker from the WS-V series, designed to provide comprehensive protection against earth leakage, overload, and short circuits in industrial and commercial power distribution systems. Combining a thermal-magnetic trip unit with high-speed earth leakage detection, it delivers reliable protection for personnel and equipment. The breaker features a 30mA rated sensitivity current with a maximum operating time of 0.1 seconds, ensuring rapid disconnection under fault conditions. Its compact dimensions (75mm W \u00d7 130mm H \u00d7 90mm D) and front lug\/bar connection design make it ideal for panel builders seeking a space-efficient solution. Compliant with IEC 60947-2 and CE marked, the NV63-CV is suitable for global applications.[reference:0]<\/p>\n
