Q2M2150MT - 150 Amp Circuit Breaker

Q2M2150MT - 150 Amp Circuit Breaker

If you're trying to match a Q2M2150MT circuit breaker already installed in older equipment, the details matter. This is a 150-amp150-amp, 2-pole thermal-magnetic breaker rated 120/240 VAC, with a 10 kA A.I.C. rating. It uses a non-interchangeable trip unit and has lug terminals on the line side with 1/4-20" studs on the load side. That terminal arrangement, along with the breaker's dimensions, is worth checking carefully when you're replacing an existing unit. The Q2M2150MT measures 6.5 inches high, 3.0 inches wide, and 3.13 inches deep. For maintenance teams and electrical professionals working with legacy equipment, it provides a specific combination of size, connections, and electrical ratings that can be difficult to match by amperage alone. When the existing system calls for this configuration, the Q2M2150MT provides the form, fit, and function needed to keep compatible equipment in service. It's a straightforward thermal-magnetic breaker built to last when properly applied and operated within its ratings.

Key Features and Benefits

• 150 amp, 2-pole configuration for equipment designed around this specific breaker rating.
• Rated 120/240VAC with a 10k A.I.C. rating.
• Thermal-magnetic operation provides overcurrent protection within the breaker's stated ratings.
• A non-interchangeable trip unit maintains the breaker's fixed trip configuration.
• Line-side lug terminals provide the specified incoming connection arrangement.
• 1/4-20" load-side studs make it easier to identify whether the breaker matches an existing connection setup.
• Dimensions of 6.5" H x 3.0" W x 3.13" D provide another useful reference when checking physical fit.
• Well-suited to legacy electrical equipment that requires the Q2M2150MT or a properly verified form, fit, and function replacement.

Material Compliance and Certifications

• Specific material-compliance information and certification details are not included in the available specifications for the Q2M2150MT. If your installation requires a particular certification, agency approval, or documented material standard, confirm those requirements for the exact breaker being installed rather than assuming compliance based on the part number or breaker type.
  

Where It Works Best

• The Q2M2150MT is best suited to existing electrical systems where matching the original breaker is the priority. It's a particularly relevant option for legacy equipment requiring a 150-amp, 2-pole, 120/240VAC thermal magnetic circuit breaker with a 10k interrupting rating and this particular terminal arrangement.
