Product FAQs
7 answersWhich panelboards are compatible with the TEY380ST12 circuit breaker?
This breaker is engineered specifically for GE A-Series panelboards. It utilizes a bolt-on connection for secure mounting in commercial lighting and distribution panels.
What function does the ST12 suffix provide on this GE breaker?
The ST12 designation indicates a factory-installed 120-277VAC shunt trip. This accessory allows the breaker to be tripped remotely, which is often required for emergency shutdown systems or remote control applications.
What wire gauge is supported by the terminals on the TEY380ST12?
The included load-side lugs accept 4 AWG to 1/0 AWG wire. Both copper and aluminum conductors are supported.
Does the TEY380ST12 offer adjustable trip settings?
No, it features a fixed thermal-magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
Is this breaker suitable for direct current (DC) circuits?
Yes, while primarily used in 277/480VAC systems, it is also rated for DC applications with an interrupting capacity of 10kA at 250VDC.
What is the interrupting capacity of the TEY380ST12 at 120/240VAC?
While the breaker is rated for 14kAIC at 480/277VAC, it provides a higher interrupting capacity of 65kAIC when installed in 120VAC or 240VAC systems.
Will this breaker arrive with GE or ABB branding?
Because ABB acquired GE Industrial Solutions, the TEY380ST12 may ship with either GE or ABB branding, or a combination of both on the packaging. The physical breaker and its compatibility remain identical.
