B-LINE LGE340033GC – Frequently Asked Questions
1) Will the Eaton LGE340033GC hold up on a 480V system, and what is its interrupting rating?
The LGE340033GC is rated 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 18 kAIC at 600 Vac. On a 480V distribution system you get 35 kAIC of interrupting capacity, so compare that against the available fault current at the point of installation before you set it. It runs on 50-60 Hz systems.
2) Is the LGE340033GC a 400 amp three-pole breaker, and can it be loaded continuously to 400A?
Yes. It is a three-pole, 400A LG-frame molded case breaker and it is 100% rated, meaning it can carry its full 400 amp rating continuously in the proper enclosure rather than being derated to 80 percent. That matters when you are sizing for a continuous load like lighting or a large motor feeder.
3) Does this Eaton Series G LG breaker have thermal-magnetic or electronic trip?
Electronic trip, LS (long time and short time) trip unit. That gives you adjustable long-time and short-time settings for coordination with downstream devices, which a fixed thermal-magnetic breaker does not. If your drawings call for an instantaneous element or ground fault protection, an LS unit is not the same thing as an LSI or LSIG unit.
4) What shunt trip voltage does this LG-frame breaker come with?
It ships with a 12-24 Vac/dc shunt trip installed on the left terminal, same side. If your control scheme drives the shunt trip from a 120V circuit, this is the wrong coil voltage for you and you will need a breaker built with the matching accessory.
5) Can I use the LGE340033GC to feed HVAC equipment?
Yes. The LG breaker is HACR rated, so it is acceptable for heating, air conditioning, and refrigeration multi-motor and combination-load equipment branch circuits where the nameplate calls for an HACR type breaker.
6) Does the LGE340033GC come as a complete breaker with terminals, or do I have to order lugs separately?
It is supplied as a complete breaker with both line and load terminals included. Mounting hardware is metric, so use metric fasteners when you bolt it in rather than assuming inch hardware from an older panel.
7) How much space and weight do I need to plan for when mounting this Eaton 400A LG breaker?
The breaker measures 5.48 in height, 5.48 in width, and 4.09 in length, and it weighs 15.3 lb. At that weight it is a two-hand lift into a panel, and it needs solid backing, not a light mounting pan.
