Product FAQs
5 answersWhich panelboards are compatible with the TEY145 circuit breaker?
This breaker is designed specifically for installation in GE A-Series lighting panelboards. It utilizes a bolt-on connection to secure directly to the panel bus.
What wire sizes and materials are supported by the terminals on this breaker?
The factory-installed lugs accept 10 to 4 AWG copper conductors or 8 to 4 AWG aluminum conductors.
Can the TEY145 be utilized in DC electrical systems?
Yes, it carries a direct current rating of 125VDC with a 10kA interrupting capacity, making it suitable for specific DC control or distribution applications.
Why might my TEY145 breaker have ABB branding instead of GE?
ABB acquired GE Industrial Solutions. As a result, newly manufactured TEY series breakers may carry the ABB logo. The physical dimensions, mounting, and electrical characteristics are identical regardless of the brand name printed on the label.
Are the trip settings on the TEY145 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) protection parameters are factory calibrated and cannot be modified in the field.
