Nader Circuit Breaker

How leakage circuit breaker selection? To everyone's safe use, must pay attention to the principle of selection leakage circuit breakers, here to share with you, I hope you can benefit: a: to select the total leakage circuit protection ① trunk or the entire network based on the normal leakage curre...

Breaker interrupter way roughly divided into two ways. (1) horizontal arc blow type. With horizontal blowing interrupter switch, when opening the movable, stationary arcing contacts separate, the heat of vaporization and decomposition of the oil. The pressure in the arc chamber rapidly increases, whe...

① breaking capacity must meet the requirements. Should be greater than the flow rate off the circuit breaker short-circuit capacity of the on-off circuit, when the main power circuit breaker because of the increased capacity of the main grid breaking capacity can not meet the requirements, the acce...

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...
