QDM22100TN - 100 Amp Circuit Breaker

QDM22100TN - 100 Amp Circuit Breaker

The QDM22100TN is a 2-pole, 100 amp thermal magnetic circuit breaker with a 25kA interrupting rating at 240VAC. It is equipped with a non-interchangeable trip unit, lug terminals on the line side, and 1/4-20 stud connections on the load side. These features make it a direct replacement for applications that require this specific configuration.

Thermal magnetic breakers combine two methods of protection in one device. The thermal element responds to sustained overloads, while the magnetic element reacts to higher fault currents. The factory-installed trip unit cannot be changed, so the breaker maintains its original trip characteristics throughout its service life.

If you're replacing an existing breaker, it's important to confirm the part number, amp rating, pole count, interrupting capacity, and connection style before installation. Matching these specifications helps ensure compatibility with the equipment already in service.

Where It Works Best

• The QDM22100TN is commonly used in commercial and industrial electrical distribution systems that require a 100 amp, 2-pole Type QDM breaker with a 25kA interrupting rating at 240VAC. It is a suitable choice for maintenance and replacement work where the existing equipment uses line-side lug terminals and load-side 1/4-20 stud connections.
