Q2M2125 - 125 Amp Circuit Breaker

Q2M2125 - 125 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, getting the details right matters. The Q2M2125 is a 125-amp, 2-pole thermal-magnetic circuit breaker rated at 10 kAIC at 120/240 VAC. It uses a non-interchangeable trip unit and has 1/4-20" studs on both the line and load sides, so it's important to compare the connection style with the breaker already installed. The Q2M2125 measures 6.5" high, 3.0" wide, and 3.13" deep. That combination of size, ratings, and connections makes it suitable for maintaining compatible electrical equipment where the goal is to match the original breaker's form, fit, and function. Simply put, if you're working on an existing system that calls for a Type Q2M breaker, these are the specifications you'll want to check. The breaker is built to last when correctly applied, installed, and maintained.

Key Features and Benefits

• 125A rating for compatible circuits requiring a 125 amp breaker.
• 2-pole design for applications calling for this pole configuration.
• Rated 10k AIC at 120/240VAC.
• Thermal-magnetic operation provides overcurrent protection in accordance with the breaker's specified characteristics.
• Non-interchangeable trip unit keeps the trip configuration fixed.
• 1/4-20" studs on the line and load sides provide a clearly defined connection arrangement for compatibility checks.
• Type Q2M configuration for use in electrical equipment designed to accept this breaker type.
• Dimensions of 6.5" H x 3.0" W x 3.13" D make it easier to compare physical fit with an existing breaker.

Material Compliance and Certifications

• No specific material compliance, environmental certification, agency listing, or certification information was included in the available specifications for the Q2M2125. If your facility or application requires a particular certification or compliance standard, check the markings and documentation for the individual breaker before installation. Compliance should never be assumed from the part number alone.

Where It Works Best

• The Q2M2125 circuit breaker is primarily suited to maintenance and replacement work involving compatible existing or legacy electrical equipment. It can be a good fit for commercial, industrial, and facility-maintenance applications where the existing system calls for a 125A, 2-pole Q2M thermal-magnetic breaker with a 120/240VAC rating and a 10k AIC interrupting capacity.
