GREENWATT® is a leading China AC800V MCCB 320A Circuit Breaker MX OF manufacturer. The ZAM6HU AC800V MCCB 320A Circuit Breaker MX OF is suitable for AC frequency 50/60Hz circuits, with rated working voltage of up to AC800V and a rated working current of up to 800A. The function of this circuit breaker in the includes connecting, disconnecting, and carrying the rated current. When the circuit experiences overloading, short circuit, or undervoltage, it can provide stable and reliable for the circuit and electrical equipment. The ZAM6HU AC800V MCCB 320A Circuit Breaker MX OF has a working voltage of AC800V and an insulation of up to AC1150V, making it suitable for use in higher voltage distribution systems and ensuring stable performance in high-altitude areas. Its ultimate shortircuit breaking capacity at AC800V is 36.5kA, which has a significant effect on reducing the harm caused by short circuits to equipment circuits. This product is widely used in new energy, power, and industrial industries.
• 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.
