Overview

The GE THQB1125 is a single-pole bolt-on circuit breaker rated at 25 amps for use in 120/240Vac electrical systems. Its bolt-on mounting style creates a mechanically secure connection inside the load center, reducing the risk of loosening under vibration or thermal cycling compared to plug-in alternatives. With a 10,000 AIC interrupting capacity at both 120V and 240V, this breaker can safely clear significant fault currents, making it suitable for both residential branch circuits and light commercial distribution panels.

The THQB1125 carries HACR certification for heating, air conditioning, and refrigeration circuits, as well as an SWD rating that qualifies it for switching duty applications where the breaker may be used as a regular on/off switch. Its fixed long-time and instantaneous trip elements provide dependable overcurrent and short-circuit protection without requiring manual adjustment. At just one inch wide per pole, it conserves valuable panel space while delivering the robust protection expected from the GE Q-Line series.
