Technical Parameters
3200A(3P) Air Circuit Breaker Fixed Type Drawer Type Air Circuit Breaker
The 3200A(3P) Air Circuit Breaker (hereinafter referred to as the circuit breaker) is suitable for power distribution networks with a frequency of 50Hz, rated working voltage of 400V and 690V, and rated current from 630A to 6300A. It is used to distribute electrical energy and protect lines and power equipment from damage caused by overload, undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has intelligent protection functions, precise selective protection, which can improve the reliability of power supply and avoid unnecessary power outages. It features compact structure, small size, and high breaking capacity. The enclosed contact system achieves zero arc flash. The intelligent controller has functions such as testing, load monitoring, large information display, on-site programming, and communication, enabling complete three-stage or four-stage protection.
