Product FAQs
6 answersWhich panelboards are compatible with the THQB32060-TQSTA8 breaker?
This bolt-on breaker is designed specifically for GE A-Series panelboards and GE AQ lighting panels. It will not fit in standard residential plug-on load centers.
What does the TQSTA8 suffix mean on this GE circuit breaker?
The TQSTA8 suffix indicates that the breaker comes with a factory-installed 24VDC to 48VDC shunt trip. This accessory allows the breaker to be tripped remotely by applying a control voltage.
What wire gauge is required for the lugs on this 60A breaker?
The box lugs on this unit accept wire sizes ranging from 8 AWG to 3 AWG. Both copper and aluminum conductors are supported.
Is this breaker suitable for 480V commercial systems?
No. The THQB32060-TQSTA8 has a maximum voltage rating of 240VAC and an interrupting capacity of 10kA at that voltage. It cannot be used in 480V or 277V applications.
How is this breaker secured inside the panel?
It uses a bolt-on mounting style. The breaker must be physically bolted to the bus bars of the panelboard, which provides a secure connection typically required in commercial and industrial environments.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic mechanism provides two types of protection. The thermal element responds to prolonged overloads (Long-Time), while the magnetic element trips immediately during severe short circuits (Instantaneous).
