Product FAQs
5 answersWhich panelboards are compatible with the THQB2130ST1 circuit breaker?
This Q-Line bolt-on breaker is designed for use in GE A-Series panelboards, including AL, AQ, ALC, AQC, and Spectra series commercial lighting panels.
Can I install the THQB2130ST1 in a standard GE residential load center?
No. The THQB series features a bolt-on connection designed specifically for commercial panelboards. Standard GE residential load centers require THQL series plug-in breakers.
What does the ST1 suffix mean on the THQB2130ST1?
The ST1 suffix indicates that the breaker includes a factory-installed 120VAC shunt trip accessory. This allows the breaker to be tripped remotely via an external control signal for emergency shutdowns or automated systems.
How does the integrated shunt trip on the THQB2130ST1 enhance electrical safety?
The 120VAC shunt trip allows the breaker to be wired to emergency stop buttons, fire alarm relays, or other safety interlocks. When energized, it instantly opens the circuit to disconnect power from critical equipment during an emergency.
Why might my THQB2130ST1 breaker arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. As a result, current production of this exact catalog number may feature ABB, GE, or GE by ABB branding. The physical dimensions, mounting, and performance specifications remain completely identical.
