Nader Circuit Breaker

Select circuit breaker breaking capacity which depends on the short circuit capacity of the power system. Rated capacity and impedance voltage, internal resistance of the power line voltage distribution system short-circuit capacity factor depends on the transformer. You said TCL for miniature circui...

(1) Low voltage circuit breaker of the rated voltage and rated current is not less than the normal operating voltage line and the load current is calculated. Setting current (2) heat release load should be equal to the rated current is controlled. Instantaneous tripping (3) electromagnetic release se...

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...
