Residual Current Circuit Breaker

This device is important in electrical wiring installation.It is a life guard device to protect from electric shock.Others circuit breaker only can detect the fault from over current and short circuit but cannot detect the current leakage.

That why RCCB is very important.Only this device can detect the current leakage.The current leakage can cause the injury or dead for human and can lead to fire hazard.When design the distribution panel board,please make sure this device include in our planning to install..it for consumer safety and avoid equipment from damage. read more

Magnetic Contactor

Magnetic contactor is common used in automation industry for motor control application.It is function basically like “relay”.The power source into the coil of winding,it like the solenoid operation.It can delivery a big ampere to¬† the loads and very long lasting and high durability.

When the power is “on”,it energized the coil and make plunger move and the switch contact is change from normally open to closed position.It allowed the current move from input terminal to output terminal.Then if we connected to the 3 phase motor,it will running :D
