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.
• High mechanical life (15000) and electrical life (2000);
• Short arc distance: Equipped with a standard arc shield and three-layer arc extinguishing metal partitions, it prevents secondary system failures caused by spraying during disconnection;
• Superb current limiting capability;
• Enhanced insulation performance, with electrical clearance and creepage distance complying ; No derating with reverse polarity connections;
• Resistance to humidity, salt mist, and mold;
• New single-break structure, more stable and reliable than double-break.
Certification: CB CCC
• Technology for preventing drop-out during contact opening by minimizing repulsion at the low point of the moving contact;
• Arc extingu technology, achieving shorter arc duration;
• Handle design that keeps the operator safe by being far from the arc extinguishing area.
