Detail Question about Elcb Breaker
For instance “P” refers to the number of poles, which represents the number of wires the circuit breaker can accommodate. Here’s an explanation of different pole configurations:
- 1P: Connects to one live wire.
- 2P: Connects to one live wire and one neutral wire.
- 3P: Connects to three live wires.
- 4P: Connects to three live wires and one neutral wire.
For converting three-phase electricity to 220V for lighting purposes, a 3P circuit breaker doesn’t require a neutral wire. However, if you need to achieve 220V voltage using a 4P circuit breaker, you can utilize one live wire and one neutral wire. Therefore, in such cases, it is recommended to use a 4P circuit breaker.
In conclusion, Formula for calculation: Total power (W) ÷ Voltage (in three-phase systems, typically 380V) = Rated current (A) (It is recommended to choose a higher-rated current).
When you receive a circuit breaker, the handle should be in the middle position, which is the initial state. To use it, you need to pull the handle downwards until it hooks at the bottom. But, never dismantle the circuit breaker on your own due to lack of knowledge about its operation. Any consequences resulting from dismantling will be your own responsibility. Above all, If you have any doubts, feel free to consult the customer service personnel.
