The SL7 series high breaking capacity mini circuit breaker (MCB) is engineered for use in AC 50/60Hz electrical systems, with a rated voltage of 230V (single - pole, two - pole) or 400V (three - pole, four - pole) and a rated current range of 1A to 63A. It provides reliable overload and short - circuit protection, and can also be used for infrequent switching under normal operating conditions. This versatile breaker is widely applied in industrial, commercial, and household electrical setups, ensuring electrical safety across various environments.
Compliance with the IEC 60898 standard guarantees the product's quality and safety performance. The breaker is available in multiple pole configurations: 1P, 2P, 3P, and 4P, catering to different electrical circuit requirements. The rated current options (1A, 2A, 4A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A) allow for precise matching with the load characteristics of various circuits.
Regarding the tripping curves, the SL7 series offers B, C, and D curves to suit different application scenarios. The B curve operates between 3 and 5 times the rated current (In), making it ideal for circuits with low inrush currents, such as those with resistive loads. The C curve, with a tripping range of 5 to 10 In, is suitable for circuits with moderate inrush currents, like those with inductive loads (e.g., motors with soft start). The D curve, tripping between 10 and 14 In, is designed for circuits with high inrush currents, such as those with heavily inductive or capacitive loads.
The electro - mechanical endurance of the SL7 series exceeds 6000 cycles, ensuring a long service life even under frequent switching operations. In terms of technical specifications, it features an electric - type operation, a normal - type speed, air as the arc - extinguishing medium, and a fixed installation method. Structurally, it is a miniature circuit breaker (MCB) with a low - voltage circuit breaking capacity. Functionally, it serves as a conventional circuit breaker, providing circuit - breaker failure protection, overcurrent protection, overvoltage protection (OVP), and residual current circuit breaker (RCCB) capabilities, and it is CE - certified.
