THHQB1125 - 25Amp Circuit Breaker

THHQB1125 - 25 Amp Circuit Breaker

The THHQB1125 is a 25 amp, single-pole circuit breaker built for use in compatible Q-Line panelboards where dependable branch circuit protection is required. Designed with a bolt-on mounting configuration, this breaker provides a secure connection and helps protect electrical systems from overloads and short circuits before damage can occur.

With a 22kA interrupting rating at 120VAC, the THHQB1125 is commonly found in commercial facilities, industrial environments, and other applications where higher fault-current capabilities are important. Its compact molded case design allows it to fit into space-conscious panel layouts without sacrificing performance. Because it carries an HACR rating, it can also be used in approved heating, air conditioning, and refrigeration applications.

Whether you're replacing an existing breaker during maintenance or updating a panel as part of a larger electrical project, the THHQB1125 offers a practical solution for protecting circuits and connected equipment.
