Siemens IEC Miniature Circuit Breaker
IEC style miniature circuit breakers (MCB), according to ENNEC 60 898, are not always permitted in North America. For this reason, MCBs were developed that were based on the miniature circuit breakers of the 5SY series and met the special requirements of UL 489. Within the sphere of influence of NEMA (National Electrical Manufacturers Association) and ANSI (American National Standards Institute) MCBs are certified as a solution for protective applications and can be used for branch circuit protection in the branches of control panels and systems.The connection terminals are designed for the class: “Field wiring”.
