AC800V MCCB 250A Circuit Breaker

GREENWATT® is AC800V MCCB 250A Circuit Breaker manufacturer and supplier in China who can wholesale AC800V MCCB 250A Circuit Breaker. ZAM6HU AC800V MCCB 250A Molded Case Circuit Breaker is suitable for circuit environments with alternating current (AC) frequency of 50/60Hz, rated working voltage up to AC800V, and rated working current up to 800A. During circuit operation, this circuit breaker is responsible for connecting, disconnecting, and carrying rated current, and provides reliable protection for the circuit and electrical equipment in the event of overload, short circuit, or undervoltage. Given that the ZAM6HU AC800V MCCB 250A Molded Case Circuit Breaker has a working voltage of up to AC800V and an insulation voltage of AC1150V, it can adapt to higher voltage distribution systems and ensure good performance in high-altitude areas. Its ultimate short-circuit breaking capacity at AC800V reaches 36.5kA, effectively reducing the harm caused by short circuits to equipment and circuits. This product has a wide range of applications in industries such as new energy, power, and industry.
