Generator Circuit Breakers
Engine generator moulded case circuit breakers are designed specifically for application on diesel engine powered standby
generators where high interrupting circuit breakers are not required.
The JG through NG breakers are equipped with a special trip unit, that includes standard thermal (overload) protection and
special low magnetic pickup range (FG includes a fixed thermal/magnetic pickup). The standard thermal trip unit provides
overload protection for conductors per the National Electric Code. The low magnetic pickup range is approximately two to five
times the continuous rating and provides closer low level short circuit protection when applied on generators that have very
low short circuit capacity. This combination allows the user to customize the breaker to the generator output.
Engine Generator Circuit Breakers are suitable for reverse feed applications.
