Product FAQs
5 answersWhat wire sizes are accepted by the standard lugs on the LDB3600?
The factory lugs accommodate two 2 AWG to 500 kcmil copper or aluminum conductors per phase. Parallel conductors are necessary to safely carry the 600A load.
Which enclosures accept this L-frame breaker?
The LDB3600 is designed for Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers that accommodate L-frame unit mount breakers.
Is this breaker suitable for DC applications?
Yes, it is rated for direct current systems up to 250VDC, where it provides an interrupting capacity of 22kAIC.
Does this breaker have adjustable trip settings?
No, it features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) protection levels are factory set and cannot be adjusted in the field.
How is the LDB3600 installed in a system?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the mounting pan or chassis and uses cable connections for both the line and load sides, rather than plugging into a busbar.
