1. "Precise Protection" Thermal-Magnetic Trip Technology
During overload, the bimetallic strip slowly heats up and bends, triggering the circuit breaker to trip (sensitivity can be adjusted via Ir);
During a short circuit, the electromagnetic coil instantly engages, cutting off the circuit (Im sets the instantaneous protection threshold), balancing the needs of "preventing false tripping" and "fast disconnection".
2. "Multi-purpose" Multi-voltage Design
A single product covers 220V (household) → 380V (industrial) → 690V (high-voltage equipment), eliminating the need to stock multiple models for different voltages, reducing procurement and inventory costs.
It is compatible with common AC power distribution voltage environments and can be flexibly applied to three-phase circuits with different voltage requirements. The circuit breaker's ability to withstand surge voltages such as lightning strikes ensures equipment safety under instantaneous high-voltage interference. In the event of a short circuit fault, it can safely interrupt the circuit at the maximum short-circuit current value, effectively cutting off the faulty circuit and protecting system equipment. It adopts a molded case structure, possessing excellent insulation performance and mechanical strength. Operation is simple, with a clear "ON" indicator showing the closed circuit state. It can effectively handle overload and short-circuit faults in power distribution lines, quickly disconnecting the circuit and protecting downstream electrical equipment. It is widely used in low-voltage power distribution systems in industrial plants, commercial buildings, and other places, providing reliable protection for electrical safety and system stable operation.
