Q2M2125MT - 125 Amp Circuit Breaker

Q2M2125MT - 125 Amp Circuit Breaker

Finding the right breaker for existing equipment often comes down to the small details. The Q2M2125MT is a 125-amp, 2-pole thermal-magnetic circuit breaker with a 10 kA I.C. rating at 120/240 VAC. It is a Type Q2MT breaker and uses a non-interchangeable trip unit. One detail to pay close attention to is the connection setup: this breaker has lug terminals on the line side and 1/4-20" studs on the load side. It measures 6.5 inches high, 3 inches wide, and 3.13 inches deep. Those dimensions, along with the electrical ratings and terminal style, make the Q2M2125MT useful for you, as it maintains compatibility with legacy equipment when the replacement needs to closely match the original breaker's form, fit, and function. Its thermal magnetic design protects against overload and short-circuit conditions within the breaker's specified ratings. It's a straightforward breaker built to last in the applications it was designed to serve.
