Nader Circuit Breaker

Thermal relay works heat is generated by the current flowing into the heating element, so that the bimetal has different coefficients of expansion is deformed when the deformation reaches a certain distance, the operation to push link, so that the control circuit is opened, so that the contact loss o...

The main reason for Ontripping: misoperation, the trip actuator itself, the electrical secondary circuit. 1. When Ontripping, should first check whether staff misuse. Staff misuse There are two cases: one is a mistake; the second is on the way back due to improper protection safeguards and causing ma...

Refused fault breaker closing process, must be able to distinguish between fault coverage, the process steps: bonding a first determines whether or not the circuit breaker due to the fault line Yufu trip meter indication may be caused by the presence or absence of short-circuit current closing operat...

Predetermined low voltage circuit breaker should be mounted vertically, which, at a predetermined connecting wire for use in wire cross section (or bus), must not be too small. Low voltage circuit breaker trip unit setting current parameters and other features and selection of parameters, a good tone...

All electrical appliances are added /220(V)×1.5 power vested open space capacity, look for the nearest similar specifications can be. Household electricity switch box configuration: the master switch (GFCI) 40a, the air conditioner switch (single-pole air switch) 20a (per 1), a light switch (single-...
