For the LW8-35 vacuum circuit breaker, it is very important to set the operating current, so how to set the operating current of the LW8-35 vacuum circuit breaker?
When the current in the circuit reaches the operating current value, the circuit breaker will trip immediately-even if there is no overload in the circuit at this time. Therefore, we must choose the appropriate operating current of the circuit breaker!
The specific parameters need to be determined by the user by calculating the number of sockets in the circuit and the electrical power used on the sockets. Here is a set of reference values: C16 for lighting circuit breaker, C16 or C20 for five-hole socket circuit, C16 or C20 or C32 for three-hole socket circuit, C32 or C40 or C63 for main switch.
When choosing, you need to pay attention to the following two points:
1. The operating current of the main switch must be greater than the operating current of any branch switch.
2. The current carrying capacity of the wires in the circuit must be greater than the operating current of the circuit breaker.
