QBM22100TN - 100 Amp Circuit Breaker

QBM22100TN - 100 Amp Circuit Breaker

The QBM22100TN is a 2-pole, 100-amp thermal-magnetic circuit breaker rated for 120/240 VAC systems with a 10 kA interrupting capacity. It uses a non-interchangeable trip unit, providing a fixed 100-amp trip rating for consistent overcurrent protection. This breaker features lug terminals on the line side and 1/4"-20 studs on the load side, making it suitable for installations that require this connection style.

Thermal magnetic breakers respond to both prolonged overloads and high fault currents, helping protect electrical equipment and wiring from damage. Whether you're replacing an existing breaker or maintaining electrical distribution equipment, the QBM22100TN delivers the electrical ratings and connection configuration needed for compatible applications.

Where It Works Best

• The QBM22100TN is commonly used in commercial and industrial electrical systems where a 100 amp, 2-pole breaker is required. It can be used to protect feeders, branch circuits, distribution equipment, and other compatible power distribution applications operating on 120/240VAC systems. The combination of lug-line terminals and stud-load terminals makes it a good fit for equipment designed around that specific connection arrangement.
