Q2M3125MT - 125 Amp Circuit Breaker

Q2M3125MT - 125 Amp Circuit Breaker

If you're replacing a Q2M3125MT circuit breaker, the details matter. This 125-amp, 3-pole thermal-magnetic breaker is a Type Q2MT unit rated at 10 kAIC at 240 VAC. It uses a non-interchangeable trip unit with lug terminals on the line side and 1/4-20" studs on the load side. The breaker measures 6.5" high, 4.5" wide, and 3.13" deep. Those dimensions and connection points are worth checking closely, especially when you're working with older electrical equipment where the replacement needs to match what's already there. The Q2M3125MT is built to last and is intended for applications that call for its specific electrical ratings, pole configuration, physical size, and terminal setup.

Key Features and Benefits

• 125A, 3-pole configuration for equipment designed around these specific ratings.
• Thermal-magnetic operation provides overcurrent protection.
• Rated 10k A.I.C. at 240VAC.
• Non-interchangeable trip unit as part of the Q2M3125MT configuration.
• Lug terminals on the line side for the required connection arrangement.
• 1/4-20" studs on the load side make it important to match the original terminal setup.
• Compact, defined dimensions help take some of the guesswork out of checking physical fit.
• A good fit for compatible legacy equipment where maintaining the original breaker configuration is important.
• Built to last when installed and used within its specified ratings.
