QBM22225TN - 225 Amp Circuit Breaker Description
QBM22225TN - 225 Amp Circuit Breaker
If you're replacing a breaker with these exact specifications, the QBM22225TN is built for the job. This is a 2-pole, 225-amp thermal magnetic circuit breaker rated for 120/240VAC with a 10kA interrupting capacity. It's commonly used in commercial and industrial electrical systems where dependable overcurrent protection is required.
Like other thermal magnetic breakers, it responds to two different types of electrical faults. The thermal element trips when a circuit remains overloaded for too long, while the magnetic element reacts almost immediately during a short circuit or other high-current fault. Together, they help protect conductors and connected equipment from damage.
One detail worth noting is the non-interchangeable trip unit. Because the trip rating is factory set, it can't be swapped for a different amperage later. That helps ensure the breaker continues to provide the protection level it was originally designed for. The breaker is also configured with lug terminals on the line side and 1/4-20 inch studs on the load side, making it suitable for installations that require those connection styles.
Whether you're replacing an existing breaker during routine maintenance or matching equipment specifications for a repair, this breaker offers the ratings and configuration needed for a straightforward replacement when the application calls for a Type QBM device.
