ABB / General Electric TQD32125 Molded Case Circuit Breaker

This Q-Line breaker installs directly into General Electric and ABB A-Series panelboards, as well as Spectra Series panelboards. It uses a standard bolt-on mounting configuration to securely connect to the bus.

The LI code signifies that this thermal-magnetic breaker provides Long-time and Instantaneous protection. The Long-time function handles standard overload protection, while the Instantaneous function provides immediate tripping during a short circuit. Both trip settings are fixed.

Yes, factory-installed TCAL25 line and load lugs are included with the breaker. These terminals accept 1 AWG through 300 kcmil copper or aluminum conductors.

Yes, this molded case circuit breaker is rated for reverse feed applications. The supply power can be safely connected to either the line or load side terminals.

If the electrical system requires a higher interrupting capacity, the THQD32125 is the direct cross-reference upgrade. It shares the exact physical footprint and 125A rating but provides a 22kAIC rating at 240VAC instead of the standard 10kAIC.

ABB acquired GE Industrial Solutions, so these components are identical in fit and function. The breaker may arrive with either ABB or GE branding on the label depending on when it was manufactured.

Yes, the TQD32125 carries an HACR rating. This certifies that the breaker is tested and safe for use with heating, air conditioning, and refrigeration systems.
