Nader Circuit Breaker

① circuit capacity does not meet the requirements. Due to ill-designed, breaking capacity circuit breaker is too small; increase due to the development of the grid, the system breaking capacity, breaking capacity circuit breaker can not meet the original requirements; breaker poor manufacturing qua...

Breakers are generally should be mounted vertically; linkage-phase circuit breaker, the level of error should not exceed 2mm; contact points, the same period of engagement should meet the requirements, should be aligned with the centerline of contact, there can not open and close jamming; should to e...

Operation and maintenance of low voltage circuit breaker should note the following: (1) Before using the rust preventive oil to the working surface of the wipe electromagnet, so as not to affect the operation value; Clear (2) regular maintenance falls automatic switch dust, so as to reduce the insula...

When the Low Voltage Circuit Breaker, it should be noted: (1) low voltage circuit breaker of the rated voltage and the rated voltage of the undervoltage release is not less than the rated line voltage; rated current (2) of the circuit breaker and overcurrent release not less than rated current route ...

Low-voltage circuit breaker is a relatively complex electrical appliances, in addition to the correct selection and adjustment, must be properly maintained to ensure its safe operation. Therefore, we should pay attention to the following points: ① prior to use anti-rust oil wipe electromagnet worki...
