3.1
Single-pole circuit breaker single-polecircuit-breaker
Applicable to single-phase circuit, with a separate electrical circuit can be separated from the main electrical circuit of the circuit breaker.
Note. The structure of the device layout in principle with the three-phase circuit breaker single-phase structure is equivalent.
3.2
Bipolar circuit breaker two-polecircuit-breaker
In the main circuit itself has two independent electrical conduction channel isolation device.
Note 1. In a single-phase circuit, the poles are connected in series and turned on and off at the same time.
