BYEM series MCCB is one of the new circuit breakers designed and developed by our company with advanced technology. Its rated insulation voltage can reach 1000V, suitable for infrequent conversion and infrequent starting of motor in circuits with AC 50 Hz, rated working voltage AC400 / 690V and rated working current up to 1600A. It has the functions of overload long time delay, short circuit short time delay, short circuit instantaneous and under voltage protection, which can protect the line and power equipment from damage.

BYEW series ACB is suitable for distribution network with AC 50Hz, rated working voltage of 400V / 690V and rated current of 200-6300A, which is used to distribute electric energy, protect lines as well as power equipments from overload, short circuit, under voltage, single-phase grounding, residual current and other faults. The selective protection of the circuit breaker is accurate, which can improve the reliability, continuity and safety of the power supply system.

BYEM6 and BYEM8 series MCB are characterized by advanced structure, reliable performance, high breaking capacity, beautiful appearance and small size. The shell and parts are made of impact resistant and high flame retardant materials. It is suitable for AC 50 Hz, rated working voltage AC230 / 400 V, rated current below 125A. It is mainly used for lighting, overload and short circuit protection, isolation of distribution lines and equipments in the office buildings, residential buildings and similar buildings, and it can also be used as normal line infrequent conversion.
