THQB2125 - 25A Circuit Breaker

THQB2125 - 25A Circuit Breaker

The THQB2125 is a 25-amp, 2-pole circuit breaker designed for use in 120/240 VAC electrical distribution systems. As a member of the Q-Line family, it uses a bolt-on mounting design that creates a firm connection to the panelboard, helping reduce movement and maintain dependable performance over time.

With a 10kA interrupting rating, the THQB2125 is intended to protect electrical circuits from overloads and short circuits before they can cause damage to connected equipment or wiring. Its 2-pole configuration makes it a practical choice for applications requiring protection across both legs of a 120/240V circuit. The breaker is also HACR rated, making it suitable for many heating, air conditioning, and refrigeration installations.

Whether you're replacing an existing breaker during maintenance or outfitting a new electrical system, the THQB2125 offers a straightforward solution for branch-circuit protection across a wide range of commercial, industrial, and residential environments.
