QBF22175TS - 175 Amp Circuit Breaker

QBF22175TS - 175 Amp Circuit Breaker

The QBF22175TS Thermal Magnetic Circuit Breaker is a 175-amp, 2-pole breaker built for reliable protection in your 120/240VAC electrical distribution applications. This QBF-style breaker combines thermal and magnetic trip technology to respond to both long-term overloads and sudden short-circuit conditions, helping you protect wiring, equipment, and electrical systems from damage. Featuring a non-interchangeable trip unit and 10kA interrupting rating, the QBF22175TS is a solid choice for installations where dependable circuit protection and proper breaker configuration are essential. The breaker includes 1/4-20" studs on both the line side and load side, allowing for secure electrical connections in compatible applications.

Key Features and Benefits
