Recommended upstream input and downstream output circuit breakers
Circuit Breaker Name
Specifications
a
Mains input circuit breaker
2500 A/3P
Bypass input circuit breaker
2500 A/3P
Downstream output circuit breaker
The system has a general output switch. There is
no need to add an external circuit breaker.
a: recommended model when the short-circuit current where the circuit breaker is located is
less than 65 kA
The upstream input circuit breakers recommended in the table are for reference only.
If multiple loads are connected, specifications for branch circuit breakers must not exceed the
recommended specifications.
The circuit breaker selection principle is to protect loads and cables, and the cascading principle is to
realize specific protection.
