Air circuit breaker, also called universal circuit breaker, is suitable for AC 50Hz/60Hz, with rated current of 200 A ~ 7500 A, rated isolation voltage of AC1000V/1250V, rated working voltage of AC220/230/240V, AC380/400/415V, AC440/480V, AC660/690V, etc. At the same time, it also has isolation function. Circuit breakers have multiple protection functions, which can not only achieve high-precision selective protection, but also avoid unnecessary sudden power failure and improve the reliability and safety of power supply system.

SXM2 series Plastic Moulded Case circuit breakers are suitable for infrequent switching and motor starting in circuits with AC 50/60Hz, rated working voltage up to AC690V and rated working current up to 800A. The circuit breaker has the functions of overload, short circuit and undervoltage protection, which can protect the line and power supply equipment from damage. Products are widely used in new energy, electric power, industrial control, real estate, power supply, telecommunications, rail transit, industrial (public) construction and other industries.

VAS1-12 series sealed vacuum circuit breakers are indoor AC high-voltage switchgear, which are suitable for three-phase AC power system with rated voltage of 12kV and frequency of 50Hz, and used as protection and control appliances. Widely used in indoor air-insulated switchgear. It conforms to GB/T1984, DL/T403 and other related standards, and its performance meets the requirements of C2-E2-M2 circuit breakers. VAS1-12 series sealed vacuum circuit breakers can meet all kinds of operation of power grid in normal or accident state, including closing and breaking load current and short-circuit current.
