Product FAQs
9 answersWhat panelboards accept the TEYL3025B circuit breaker?
The TEYL3025B is designed specifically for installation in commercial GE A-Series panelboards. It features a bolt-on mounting configuration that fastens directly to the interior busbars.
Can the TEYL3025B be used on DC circuits?
Yes, this breaker is rated for DC systems. It provides an interrupting capacity of 42kAIC at 125VDC and 35kAIC at 250VDC.
What wire sizes do the lugs on this breaker accept?
The load side lugs are designed to accept wire sizes ranging from 10 AWG to 4 AWG. The terminals are rated for use with both copper (Cu) and aluminum (Al) conductors.
Is the TEYL3025B interchangeable with standard TEY breakers?
The TEYL3025B shares the same physical dimensions and bolt-on footprint as standard TEY frame breakers used in GE A-Series panelboards. However, the TEYL version provides a higher interrupting rating of 65kAIC at 277/480VAC.
Are the trip unit settings on the TEYL3025B adjustable?
No, this breaker features a non-interchangeable, fixed thermal magnetic trip unit. Both the Long-Time (L) and Instantaneous (I) trip functions are factory set and cannot be adjusted in the field.
What is the maximum AIC rating for this breaker at 240VAC?
While it offers 65kAIC at 277/480VAC, the TEYL3025B features a maximum interrupting rating of 100kAIC when used on 120/240VAC or straight 240VAC systems.
Is the TEYL3025B a plug-in or bolt-on breaker?
It is a bolt-on circuit breaker. You must mechanically secure it to the panelboard busbars using screws, which provides a highly reliable electrical connection for commercial and industrial applications.
Is the TEYL3025B suitable for reverse feeding?
Yes, manufacturer specifications indicate that the TEYL3025B is suitable for reverse feed applications. Always verify local electrical codes and panelboard labeling before backfeeding a circuit breaker.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, the TEYL3025B may be shipped with either General Electric or ABB branding on the label, but the physical product is identical and fully interchangeable.
