Product FAQs
5 answersWhich panelboards are compatible with the DA2350?
The DA2350 is designed for use in legacy Westinghouse CDP panelboards, FDP switchboards, and compatible Eaton panelboards.
What type of wire can be used with the DA2350?
The standard lugs on this breaker are rated for both aluminum and copper conductors, accepting wire sizes from 250 kcmil to 500 kcmil.
What does a feed-thru connection mean for the DA2350?
As a feed-thru circuit breaker, the DA2350 utilizes mechanical lugs for both the line and load side terminations rather than plugging directly into a busbar.
Can the trip curve be adjusted on the DA2350?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings, providing non-adjustable long-time and instantaneous protection.
What is required to upgrade a DA2350 to a newer breaker frame?
The DA frame is a legacy product originally manufactured by Westinghouse. When replacing it with a newer Eaton Series C K-Frame in a panelboard application, a TAD3 spacer kit is required for proper fitment.
