Product FAQs
6 answersWhat is the difference between the Eaton LD3350 and the HLD3350?
Both are 350A, 3-pole Series C L-Frame circuit breakers, but they have different interrupting capacities. The HLD3350 is the high-interrupting version, rated at 65kAIC at 480VAC and 100kAIC at 240VAC. The standard LD3350 is rated at 35kAIC at 480VAC and 65kAIC at 240VAC.
Which enclosures and panelboards are compatible with the HLD3350?
This unit mount L-Frame breaker is designed for installation in Eaton Series C panelboards, switchboards, and motor control centers. It is also backward compatible with many classic Westinghouse and Eaton Pow-R-Line C panels that accept L-Frame breakers.
What wire size is accepted by the standard lugs on the HLD3350?
The standard feed-thru lugs accept dual wire configurations, accommodating two conductors ranging from 3/0 AWG up to 350 kcmil per phase.
Can the HLD3350 be used in DC power applications?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, with a DC interrupting rating of 25kAIC. It is suitable for specific industrial DC control and distribution circuits.
Does the HLD3350 feature adjustable trip settings?
No, this specific breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without field adjustability. If you need adjustable settings, you would need an L-Frame breaker with an electronic trip unit, such as the Digitrip 310+.
Is the HLD3350 a unit mount or I-line style breaker?
The HLD3350 is a unit mount, or bolt-on, circuit breaker. It is designed to be bolted directly to the bus or mounting pan and is not compatible with I-line or plug-on panelboard designs.
