Product FAQs
6 answersWhy is the LG3600 specified for engine generator applications?
This Series G breaker includes a specialized low magnetic pickup range tailored for diesel standby generators. Because generators typically produce lower short-circuit currents than utility power sources, this optimized pickup ensures rapid clearing of low-level faults.
Can the Eaton LG3600 circuit breaker be reverse fed?
Yes. Eaton engine generator molded case circuit breakers, including the LG3600 model, are engineered to be fully suitable for reverse feed applications.
What size wire is compatible with the standard terminal lugs on the LG3600?
The standard lugs provided with this breaker accommodate two 400 kcmil to 500 kcmil aluminum or copper (Al/Cu) conductors per phase.
Is the LG3600 a direct drop-in replacement for legacy Series C L-frame breakers?
No. The Series G LG3600 features a more compact physical footprint than older Series C models like the LD or HLD. Upgrading from a Series C to a Series G breaker typically requires mounting modifications and different connecting hardware.
What equipment is the LG3600 unit-mount breaker designed to fit?
It is engineered for installation in Eaton Pow-R-Line panelboards, industrial switchboards, and integrated diesel engine generator enclosures.
Are internal accessories field-installable on the LG3600?
Yes. The Series G L-frame design supports common field-fit internal accessories, allowing installers to easily add auxiliary switches, bell alarms, and shunt trips on site.
