Product Overview This circuit breaker is a low-voltage protection device designed for AC 50/60Hz power distribution networks with rated voltages up to 400V and currents up to 63A, suitable for industrial, commercial, and residential electrical systems. It integrates comprehensive safety and operational safeguards: High-sensitivity Residual Current Detection (RCD) technology provides indirect contact protection to mitigate electric shock risks, while overload long-time delay protection and short-circuit instantaneous tripping ensure precise fault current interruption, preventing equipment damage and fire hazards. The device also supports infrequent circuit switching and intermittent motor start-stop operations, meeting flexible control demands in standard power distribution scenarios. Key Features & Applications Featuring a modular compact design compatible with global power standards, it is ideal for data centers, manufacturing facilities, and building distribution panels, particularly in environments requiring high power continuity and safety. The thermomagnetic dual-protection mechanism guarantees stable overload response and rapid short-circuit breaking, enhanced by 50/60Hz frequency compatibility for robust system reliability. With a durable construction and rail-mounted quick installation, it serves as a reliable solution for modern smart grids, balancing safety, efficiency, and ease of maintenance.
