Q2M3225MB - 225 Amp Circuit Breaker

Q2M3225MB - 225 Amp Circuit Breaker

The Q2M3225MB Thermal Magnetic Circuit Breaker is a 225-amp, 3-pole breaker used in your electrical distribution equipment that calls for a Q2MB breaker type. This model includes a non-interchangeable trip unit and carries a 10kA interrupting rating at 240VAC. It features 1/4-20" studs on the line side and lug terminals on the load side, matching the connection requirements of compatible equipment.

For facilities maintaining existing electrical systems, the Q2M3225MB offers a practical replacement option when the original breaker specifications need to be maintained. Its thermal magnetic trip design helps you protect connected circuits from overloads and short-circuit conditions, while its established breaker configuration makes it a straightforward fit for approved applications. The breaker's construction is intended for continued use in properly maintained electrical systems where matching ratings, dimensions, and connections are important.
