1SM6-100 high breaking small molded case circuit breakers (hereinafter referred to as circuit breakers) for AC 50Hz / 60Hz, rated voltage single-phase 220 / 230V, three-phase 380 / 400V and below, rated current up to 100A of the lighting distribution system or motor power distribution system, as the line overload and short circuit protection, but also in the normal circumstances, infrequent on-off electrical equipment and lighting lines.
1SM6-63 high breaking small molded case circuit breakers (hereinafter referred to as circuit breakers) for AC 50Hz / 60Hz, rated voltage single-phase 220 / 230V, three-phase 380 / 400V and below, rated current 1-63A lighting distribution system or Motor power distribution system, as the line overload and short circuit protection, but also in the normal circumstances, infrequent on-off electrical equipment and lighting lines.
1SM6-32 / 1SM6K-32 series of small molded case circuit breakers (hereinafter referred to as circuit breakers) for AC 50Hz / 60Hz, rated voltage 220 / 230V, 1SM6-32 rated current to 20A, 1SM6K-32 rated current to 40A circuit , Overload and short circuit protection of the electrical circuit. The internal use of bipolar structure design, one of the very protection, a very unprotected, bipolar at the same time closed, disconnected, so as to solve the residential single-phase end of the switch only the use of a variety of hidden dangers, Safe and reliable. So it is currently the best residential distribution protection. This product complies with GB10963, IEC60898 standards.
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.
