Overall and Installation Dimensions

Core Performance and Reliability
High-precision protection response: Using high-precision electromagnetic tripping technology, the protection response is fast and accurate, with strong consistency and is not affected by power supply fluctuations. It also has dual functions of overcurrent/short-circuit protection and leakage protection to ensure line safety.
Superior Electrical Performance: High-performance silver alloy contact design achieves low contact resistance, extending electrical life and reducing maintenance requirements. An advanced arc extinguishing system safely extinguishes the powerful arc formed during high fault current interruptions, minimizing damage to connected equipment and the circuit breaker itself, ensuring operational integrity after a fault.
Stable breaking capacity: Rated short-circuit breaking capacity is up to 6KA, suitable for lines with AC 50/60Hz, rated voltage 240V, and rated working current up to 63A. It can stably interrupt fault current under specified working conditions.
Structure and installation advantages
Compact/Modular Design: With both compact and modular designs, the small size saves valuable space in the distribution box while simplifying the installation and wiring process and improving construction efficiency.
Standardization and Compliance: Complies with IEC61009-1 standards, product design specifications, reliable performance, accurate protection characteristics, and adapts to general industry installation and usage requirements.
Applicable Scenarios and Value Positioning
Widely applicable scenarios: Suitable for industrial and commercial lighting distribution lines, and can meet the line protection needs in such scenarios.
Long-term value orientation: The product design focuses on excellent performance, durability and long-term value. Choosing this product is equivalent to investing in "high efficiency + high reliability", which can provide guarantee for the long-term safe operation of the line.
