QDA32125 - 125 Amp Circuit Breaker

QDA32125 - 125 Amp Circuit Breaker

When your dependable circuit protection matters, the QDA32125 delivers the performance electricians and maintenance teams expect. This 125-amp, 3-pole molded case circuit breaker features a thermal-magnetic trip unit that reacts to both sustained overloads and sudden short circuits, helping you protect valuable electrical equipment while supporting safe system operation. Its I-Line plug-on design allows for straightforward installation in compatible panelboards, making it a practical choice for new projects, system upgrades, or replacing an existing breaker with the same specifications. Built on the Q-Frame platform, the Type QDA32125 is rated to interrupt up to 25kA at 240VAC, making it well suited for many commercial and industrial power distribution systems. Whether it's supplying power to HVAC equipment, motor loads, distribution panels, or manufacturing equipment, this breaker combines the electrical ratings professionals look for with a design intended for consistent, day-to-day performance.
