1SM1 Series Moulded Case Circuit Breaker is applied to the electric circuit with rated current ranging from 10A to 2000A (ac 50Hz), rated isolation voltage of 690V and rated operating voltage below 690V. 1SM1 Circuit Breaker is generally used in power distribution system, while circuit breaker with rated current of 400A and C-type, N-type, S-type circuit breakers can also be used to protect electric motor. Generally speaking, these circuit breakers start working when infrequent conversion occurs in the circuit or infrequent launch occurs in the electric motor.

Circuit breaker in power distribution system can not only distribute power but can also protect the circuit and power from overload, short circuit and under voltage.

Circuit breaker in electric motor, it helps to break the current in squirrel-cage motor when it starts or operates under the operating voltage of 400V. It can also protect the motor from overload, short circuit and under voltage.

1SM2Z series of intelligent molded case circuit breaker (hereinafter referred to as circuit breakers), the company uses the international advanced design and manufacturing technology research and development of new circuit breakers. The rated insulation voltage of 800V, for AC 50Hz, rated operating voltage

400V and below, rated current up to 800A in the circuit for frequent conversion and the motor is not frequent use of the start. The circuit breaker has the functions of overload long delay inverse time, short circuit short delay inverse time, short circuit short delay time limit, short circuit instantaneous and undervoltage protection function, can protect the line and power supply equipment from damage.

The circuit breaker has the characteristics of compact structure, small volume, high breaking, short arc, internal and external accessories, convenient and intuitive, and the user can set the necessary protection characteristics to make the selective protection, so that the circuit breaker is equipped with the upper and lower More reasonable.

The circuit breaker has the function of running current beam indicating, pre-alarm indication, overload indication, intelligent controller self-diagnosis function and trip test function, and has a grounding protection function, internal temperature monitoring function, isolation function, which represents the isolation symbol, There are communication interface products with fieldbus communication function, can communicate with the computer network, remote control, telemetry, remote control, remote and other functions.

1SM1Z series of intelligent molded case circuit breaker (hereinafter referred to as circuit breakers), the company uses advanced design, manufacturing technology to meet the needs of the market development of new circuit breakers. The rated insulation voltage of 1000V, for AC 50Hz, rated voltage 400V, rated current up to 800A for the circuit for frequent conversion purposes. Circuit breaker with demand protection, overload long delay inverse time, short circuit short delay, short circuit instantaneous, ground protection, to protect the line and power equipment from damage.
