QBM22175TN - 175 Amp Circuit Breaker

QBM22175TN - 175 Amp Circuit Breaker

When you need a 175-amp, 2-pole circuit breaker with a fixed trip unit and specific terminal connections, the QBM22175TN is built for the job. This thermal-magnetic circuit breaker is rated for 120/240 VAC. It protects against both overloads and short circuits, making it a practical choice for a variety of commercial and industrial electrical systems. One feature that sets this breaker apart is its non-interchangeable trip unit, which maintains the trip rating throughout the breaker's life. It also uses lug terminals on the line side and 1/4-20 studs on the load side, so it's important to confirm these connection styles match your existing equipment before installation. Whether you're replacing a worn breaker during routine maintenance or sourcing a compatible unit for an existing panel, the QBM22175TN delivers the electrical ratings and configuration needed for the application.
