Why should 4P DC circuit breaker be selected for DC1000V?

1. Direct current is more dangerous than alternating current.

2. The short circuit circuit normally has hundreds of amps to thousands of amps. When the 2P DC circuit breaker is used in the DC1000V service, the subsection capability is greatly reduced and the safety is greatly reduced, so it is necessary to connect the circuit breaker in series to improve the subsection capability and the service safety

3. 2P DC circuit breaker is easy to burn off after short circuit, 4P DC circuit breaker can be used for many times after short circuit
