Specifications

YCB7 series circuit breaker is used in lighting distribution system or motor distribution system for protecting overload and short circuit in the system. The product is neoteric in structure, lig ht in weight, reliable and excellen t in performance. Its frame and parts adopt plastics of high fire resistant and shockproof. The product, with long life, is mainly used in AC 50Hz/60Hz single pole 240V or two, three, four poles up to 415V circuit for overload and short circuit protection, as well as for unfrequently switching electric equip ment and lighting circuit in normal case. The products comply with IEC 60898 & GB10963-1999.

General
