Product FAQs
8 answersWhat enclosures are compatible with the Eaton LGE340033W circuit breaker?
This Series G LG-frame breaker is designed for installation in Eaton panelboards, switchboards, and motor control centers.
What protection functions are included in the LGE340033W trip unit?
It is equipped with a Digitrip 310+ electronic trip unit that provides adjustable Long-Time (L) and Short-Time (S) protection. It does not include ground fault protection.
How is the LGE340033W mounted inside an enclosure?
This is a unit-mount circuit breaker. It bolts directly to the mounting pan or chassis of the panelboard or switchboard rather than plugging into a busbar.
What does the 33 in the LGE340033W catalog number indicate?
The 33 suffix specifies that the breaker includes a Digitrip 310+ electronic trip unit configured for Long-Time and Short-Time (LS) trip functions.
Is the LGE340033W suitable for 480V commercial electrical systems?
Yes. It is rated for up to 600VAC. When installed in a 480VAC system, it carries a maximum interrupting rating of 35kAIC.
What is the maximum continuous current rating for the LGE340033W?
The breaker is rated for a maximum continuous current of 400 amps. Because it features an adjustable electronic trip unit, the long-time pickup can be dialed down to protect circuits with lower ampacity requirements.
Can I use the LGE340033W to replace an older Cutler-Hammer LG-frame breaker?
Yes. Eaton acquired Cutler-Hammer, and their Series G breakers are fully interchangeable. The LGE340033W will directly replace older Cutler-Hammer models bearing the exact same catalog number.
Does the LGE340033W provide ground fault equipment protection?
No. The LS trip function only covers Long-Time and Short-Time overcurrents. Applications requiring ground fault protection will need a breaker with an LSG or LSIG trip unit, such as the LGE340035W.
