The SC65-63 high-breaking miniature circuit breaker is engineered with advanced structural design, ensuring dependable performance and superior breaking capacity. Its housing and internal components are constructed from impact-resistant, flame-retardant PA66 nylon material, providing enhanced safety and durability. This breaker is suitable for power systems operating at frequencies of 50Hz or 60Hz, with a rated voltage of up to 400V and currents up to 63A.
Primarily used in office buildings and residential settings, the SC65-63 MCB delivers effective protection for lighting circuits, power distribution systems, and electrical equipment against overloads and short circuits. It also supports infrequent power system transfers, adhering to international standards IEC60898-1 and GB10963.1. With a mechanical lifespan of 10,000 operations and an IP20 protection rating, this breaker guarantees long-term reliability in diverse environments.
Key features include optional 1 to 4 poles, rated currents from 1A to 63A, and a breaking capacity of 10kA. The product undergoes rigorous testing, such as thermal endurance at 55°C, and offers customizable protection modes (e.g., Type B, C, or D) for specific applications like lighting or motor circuits. Its DIN rail mounting design facilitates easy installation, making it a versatile choice for electrical panels.




Technical parameters include a rated voltage of 230V for single-pole and 400V for multi-pole configurations, with detailed current release characteristics ensuring precise tripping times under various conditions. For instance, at 1.13 times the rated current, the breaker does not trip within 1 hour, while at 1.45 times, it trips in less than 1 hour under heated conditions. This precision enhances system safety and efficiency.
