Product FAQs
7 answersWhich panelboards are compatible with the THQB32060ST1?
This breaker is compatible with GE A-Series panelboards and AQ lighting panels that accept bolt-on Q-Line circuit breakers.
What does the ST1 suffix mean on this GE circuit breaker?
The ST1 suffix indicates the inclusion of a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely, which is often required for emergency shutdown systems or automated controls.
Can I install this THQB breaker in a standard residential plug-on load center?
No. THQB breakers feature bolt-on connections designed for commercial panelboards. Most residential GE load centers require THQL plug-on breakers, which use different bus connections and are not interchangeable with bolt-on types.
What type of wiring is approved for the THQB32060ST1 lugs?
The box lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 8 AWG to 3 AWG. When terminating aluminum wire, an approved oxide inhibitor is highly recommended to prevent corrosion.
Are the long-time or instantaneous trip functions adjustable on this model?
No. This unit features a fixed thermal-magnetic trip mechanism. The 60A trip point and instantaneous thresholds are factory calibrated and cannot be altered in the field.
Will this breaker fit if my panelboard is labeled ABB instead of GE?
Yes. ABB acquired GE Industrial Solutions, and current Q-Line breakers retain the exact same physical footprint and THQB catalog numbers. An ABB THQB32060ST1 is a direct replacement for a legacy GE unit of the same part number.
How does the shunt trip mechanism on this breaker enhance electrical safety?
The integrated shunt trip allows an external 120V electrical signal to automatically open the breaker contacts. This is critical for connecting the breaker to fire alarm relays, emergency stop buttons, or equipment interlock systems for rapid power disconnection.
