Q2M3110MT - 110 Amp Circuit Breaker

Q2M3110MT - 110 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the little details matter just as much as the amp rating. The Q2M3110MT is a 110-amp, 3-pole thermal-magnetic circuit breaker rated at 10 kAIC at 240 VAC. It's a Q2MT-type breaker with a non-interchangeable trip unit, plus lug terminals on the line side and 1/4-20" studs on the load side. That terminal arrangement is worth noting when you're trying to match an existing breaker. The unit measures 6.5 inches high, 4.5 inches wide, and 3.13 inches deep, so that you can compare its physical size along with the electrical specifications before installation. For compatible legacy equipment that requires this configuration, the Q2M3110MT offers a straightforward way to maintain the original form, fit, and function. It's built to last when correctly installed, properly maintained, and used within its stated ratings.

Material Compliance and Certifications

• Specific certification listings and material-compliance information were not provided with the available specifications for the Q2M3110MT circuit breaker. If your application requires a particular certification, listing, or material standard, check the markings on the breaker and the documentation for the equipment to be installed. Compliance should never be assumed from a part number alone.

Where It Works Best

• The Q2M3110MT makes the most sense when you're maintaining compatible legacy electrical equipment and need to match an existing breaker as closely as possible. In these situations, simply finding a 110 amp breaker isn't enough. You'll want to confirm the three-pole configuration, Q2MT type, 240VAC rating, 10 kA AIC rating, physical dimensions, and terminal arrangement as well.
