Product FAQs
6 answersWhich load centers are compatible with the UBITBA220 circuit breaker?
This breaker is classified for use in Challenger Type A, Crouse-Hinds Type MH, Murray Type MP, and Thomas & Betts Type A load centers. Always verify panel labeling for approved replacement types before installation.
Can I use the UBITBA220 to replace an obsolete Crouse-Hinds TBA220?
Yes, the UBITBA220 is the direct replacement for the original Crouse-Hinds TBA220. It matches the physical dimensions and plug-in connection required for older Crouse-Hinds Type MH panels.
What wire sizes are accepted by the box lugs on the UBITBA220?
The box lugs accommodate wire gauges ranging from 14 AWG to 4 AWG. Installers should select the appropriate copper or aluminum conductors based on the 20A rating and local electrical codes.
What type of protection does the UBITBA220 provide?
It utilizes a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions. This provides standard protection against both sustained overloads and sudden short circuits.
What is the maximum fault current the UBITBA220 can safely interrupt?
This breaker has a 10kAIC rating at 120/240VAC. It is suitable for standard residential and light commercial applications where the available fault current does not exceed 10,000 amps.
Does the UBITBA220 require mounting hardware?
No, this is a plug-on breaker. It snaps directly into the busbar of compatible load centers, requiring no screws or bolt-on hardware for the panel connection.
