TQD32125 - 125Amp Circuit Breaker

TQD32125 - 125 Amp Circuit Breaker

The TQD32125 circuit breaker is a dependable choice for you to protect three-phase electrical systems in commercial and industrial environments. Rated at 125 amps, this 3-pole molded-case breaker is designed to help protect equipment and electrical circuits against overloads and short circuits while fitting into compatible Q-Line panelboards and distribution equipment.

Its bolt-on design provides a secure connection inside the panel, helping reduce movement and maintain solid electrical contact over time. The internal common trip feature allows all three poles to trip together when needed, which is especially important in protecting connected equipment and maintaining system safety. Because it’s HACR-rated, the TQD32125 is also commonly used in HVAC, refrigeration, and air conditioning systems where steady, reliable protection is important.

This breaker includes load-side lugs for added installation convenience and features a molded case housing designed for everyday use in demanding electrical applications. Whether used as a replacement part during maintenance or installed in an existing compatible system, the TQD32125 is built to last and designed for dependable operation.
