Q2M3125 - 125 Amp Circuit Breaker

Q2M3125 - 125 Amp Circuit Breaker

If you're looking for a Q2M3125 circuit breaker, chances are you already have a specific application in mind. This Type Q2M thermal-magnetic breaker is rated for 125 amps and has a 3-pole configuration, with an interrupting rating of 10 kAIC at 240 VAC. One detail worth checking closely is the connection style: the Q2M3125 uses 1/4-20-inch studs on both the line and load sides. It also has a non-interchangeable trip unit. The breaker measures 6.5 inches high, 4.5 inches wide, and 3.13 inches deep, so you can compare its physical footprint with the breaker currently installed in your equipment. For older electrical systems, those details can be just as important as the amperage rating. When your application calls for the Q2M3125 configuration, this breaker provides the form, fit, and function needed to maintain compatibility with existing equipment without changing the original system design. Its straightforward construction is built to last when properly installed, applied, and maintained within its specified ratings.

Key Features and Benefits

• 125A, 3-pole configuration for equipment designed around these specific electrical requirements.
• Thermal-magnetic operation provides overload and short-circuit protection within the breaker's rated application.
• Rated 10k A.I.C. at 240VAC.
• Type Q2M construction for compatible electrical equipment.
• Features a non-interchangeable trip unit.
• Uses 1/4-20-inch studs on both sides of the breaker—line and load.
• Measures 6.5" H x 4.5" W x 3.13" D, making physical fit easier to verify before installation.
• A good fit for maintaining compatible legacy electrical systems where matching existing breaker specifications is the priority.
• Straightforward construction that's built to last when used within its intended ratings and application.

Material Compliance and Certifications

• Material compliance, agency certifications, and listing information were not provided with the available Q2M3125 specifications, so they shouldn't be assumed. If a particular certification or compliance standard is required for your installation, check the breaker labeling and applicable equipment documentation before use.
• It's also important to verify more than just the 125-amp rating. Pole count, voltage, A.I.C. rating, dimensions, trip configuration, and terminal style should all match the equipment requirements.

Where It Works Best

• The Q2M3125 is intended for compatible electrical equipment that requires a Type Q2M, 125A, 3-pole thermal-magnetic circuit breaker with a 10kA I.C. rating at 240VAC. It's particularly relevant when maintaining older or legacy equipment where the goal is to match the breaker already specified for the system.
