No external power supply required, and circuit protection is maintained even in power-off state.<\/p>\n<p>Aiming at frequent short-circuit and overload problems in industrial scenarios, the tripping response mechanism is optimized. Uder 50KA short-circuit current, it can be quickly disconnected and quickly block the proliferation of faults and prevent damage to power distribution cabinets and backend equipment due to long-term faults.<\/p>\n<p>Adopting a four-pole synchronous action structure, the live wire and neutral wire &#8220;act and stop simultaneously&#8221; during switching. It solves the problem of excessive neutral wire current caused by unbalanced three-phase loads, especially suitable for nonlinear load scenarios such as frequency converters and servo motors, eliminating the risk of equipment voltage abnormality and burnout caused by neutral wire breakage.<\/p>\n<p>The circuit structure design is optimized to improve anti-electromagnetic interference capability, enabling stable operation in strong electromagnetic environments (such as machine shops and around frequency converters).
