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 neceary 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 4. New DZ47Z has advantages of rated short-circuit section up to 6000A, 20 square nickel-plated copper row (up to 90A current) for series, beautiful appearance, copper row is not exposed, screw hole has plug head protection cover.
