Description of ZYW1 Series Intelligent Universal Circuit Breaker
The ZYW1 series intelligent universal circuit breaker (hereinafter referred to as the “circuit breaker”) is mainly applicable to power distribution networks with an alternating current of 50Hz or 60Hz, a rated working voltage of 400V or 690V, and a rated current ranging from 200A to 6300A. It is used to distribute electrical energy and protect lines and power equipment from hazards such as overload, undervoltage, short circuit, and grounding. The core component of the circuit breaker adopts an intelligent controller, which has precise selective protection and can avoid unnecessary power outages, thereby improving the reliability, continuity, and safety of the power supply system.
This circuit breaker can be widely applied in power stations, factories, mines, and modern high-rise buildings, especially in the power distribution systems of intelligent buildings. It is also widely used in the green energy fields such as wind power generation and solar power generation.
This circuit breaker complies with the IEC60947-2 and GB/T14048.2 standards.
