997217 - 125 Amp Circuit Breaker

997217 Molded Case Circuit Breaker – 125 Amp, 2 Pole, 600VAC, ML Frame

If you're replacing a breaker in an existing setup, you already know the job isn’t about experimenting—it’s about getting the right match. The 997217 molded case circuit breaker is built to fit into compatible systems without forcing changes. It carries a 125 amp rating, uses a 2-pole configuration, and is designed for up to 600VAC applications commonly found in commercial and industrial environments. This unit features a thermal-magnetic trip, so it reacts to both long-term overloads and sudden short circuits. That’s the kind of protection most legacy systems were originally designed around. Built on an ML (J-Frame) platform, it’s intended to line up with existing equipment where form and fit matter just as much as the electrical rating. It’s straightforward, does what it’s supposed to do, and holds up over time.
