NM1LE series residual current operated circuit breaker
Circuit breaker, residual current operated circuit breaker - RCCN
NM1LE series residual current operated circuit breaker (hereinafter referred to as residual current operated circuit breaker) is one of the new residual current operated circuit breakers designed and developed by the company using international advanced technology. Suitable for AC 50Hz, rated voltage up to 415V, rated current 16A to 800A.
Its main function is to provide indirect contact protection for human shocks that are fatal. The residual current operated circuit breaker with rated residual operating current not exceeding 0.03A can also be used as supplementary protection for direct contact when other protection measures fail, but it cannot be used as the sole direct contact protection. At the same time, it can also be used to prevent electrical fires caused by contact with fault currents. It can also be used to protect the line from overload and short circuit, and can also be used as an infrequent conversion of the line.
The residual current operated circuit breaker has a small volume (equal to the corresponding molded case circuit breaker), high breaking, short arcing and residual operating current, and can be equipped with an alarm contact, a shunt release, and an undervoltage trip. Accessories, auxiliary contacts, rotating handle operating mechanism, electric operating mechanism and other accessories, and can be used in front of the board, behind the board and plug-in and other wiring methods, is the ideal product for users.
The residual current operated circuit breaker is installed vertically (ie, vertically) or horizontally (ie, horizontally).
Meet the standard: GB/T 14048.2, IEC 60947-2.
