Designed for high-power scenarios (with short-circuit current up to 50KA) such as industrial workshops and large supermarkets, it is equipped with a reinforced arc-extinguishing chamber and large-section conductive components. In case of faults, it can instantly extinguish arcs and cut off circuits, preventing equipment burnout and power distribution system paralysis caused by expanded short-circuit current, providing “hardcore” protection for high-power loads.<\/p>\n
250A high current carrying capacity, adapted to heavy-duty loads.Adopting a wide copper bar conductive structure, it features stable current-carrying capacity and can continuously bear 250A rated current. It perfectly matches heavy-duty power equipment such as large workshop motors , central air-conditioning hosts in shopping malls, and UPS incoming lines in data centers, eliminating the need for frequent replacement or capacity expansion.<\/p>\n
3P precise three-phase protection: more stable power circuits.Exclusive for 380V three-phase power systems, it enables independent monitoring and synchronous tripping of three-phase currents. It effectively prevents motor stalling and abnormal equipment damage caused by unbalanced three-phase loads and phase-loss operation, suitable for industrial power equipment (e.g., machine tools, fans, water pumps) and power trunk lines in commercial buildings, eliminating safety hazards from “phase deviation”.<\/p>","protected":false},"excerpt":{"rendered":"
