Nader Circuit Breaker

Air switch is very important in low voltage distribution network and the power of one electrical drive system, which combines the control and protection functions in a variety of. In addition to complete and break the contact circuit, a short circuit or electrical equipment can still occur. Severe ov...

First calculate the total of all electrical power P, the calculated total current number of A I = P / U, when the switch is selected to be greater than the total amount of current leakage, cut to have a certain margin, or installed in other words on the electrical will bear the remaining leakage curr...

P single circuit breaker, only the phase control (that is, FireWire), the blue line is the zero line collector, connected to the zero line or zero row of the distribution box. Your drawing is not wrong. The reality is that the place next to your breaker have access to zero line....

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...
