Product Details
1、 Scope of application
TXL7-63High score cutoffminiature circuit breaker（Mueller circuit breaker、L7 circuit breaker、10KA miniature circuit breaker with breaking capacity）It is mainly used for protection distribution lines with AC 50Hz/60Hz, rated working voltage up to 400V (380V), rated current up to 63A, and rated short-circuit breaking force not exceeding 10KA. It is used for infrequent connection, disconnection, and conversion of the line, and has overload and short-circuit protection functions. At the same time, it has powerful auxiliary function modules, such as auxiliary contacts, alarm indicator contacts, shunt release, remote release control of undervoltage release, and other modules.
Circuit breakerCompliant with GB10963.1 and IEC60898-1 standards.
