This miniature circuit breaker is designed for circuits with AC 50Hz or 60Hz, a rated working voltage of 400V and below, and a rated current ranging from 1A to 63A.
It is primarily utilized for overload and short-circuit protection in lighting systems, distribution lines, and equipment within office buildings, residences, and similar structures. Additionally, it serves as an infrequent conversion switch for lines under normal operating conditions.
Our products strictly comply with IEC60898-1 and GB10963.1 standards and have successfully obtained the CCC certification.
