Q2M2100MT - 100 Amp Circuit Breaker

Q2M2100MT - 100 Amp Circuit Breaker

Finding the right breaker for an existing electrical system often comes down to the small details. The Q2M2100MT is a 100-amp, 2-pole thermal-magnetic circuit breaker with a 10k A.I.C. rating at 120/240VAC. It uses a non-interchangeable trip unit and has a connection setup that's worth checking closely: lug terminals on the line side and 1/4-20-inch studs on the load side. The breaker measures 6.5 inches high, 3.0 inches wide, and 3.13 inches deep. If you're replacing a breaker in existing or legacy equipment, those dimensions and terminal connections can matter just as much as the amperage. The Q2M2100MT is intended for applications that call for the Q2MT configuration and matching electrical ratings. It's a straightforward, built-to-last component for keeping compatible equipment in service without changing the intended form, fit, or function.

Key Features and Benefits

• 100A, 2-pole design for compatible 120/240VAC applications.
• Thermal-magnetic operation provides the breaker's overcurrent trip functionality.
• Rated 10 kA I.C. at 120/240VAC.
• Non-interchangeable trip unit provides a fixed trip configuration.
• Lug terminals on the line side for the specified connection arrangement.
• 1/4-20" studs on the load side help identify compatibility with existing equipment.
• Type Q2MT configuration for applications specifically designed around this breaker style.
• Clearly defined dimensions make it easier to check physical fit before installation.
• Built to last when properly matched, installed, and operated within its stated ratings.

Material Compliance and Certifications

• Specific material-compliance information and certification details were not provided in the available Q2M2100MT specifications. Because requirements can differ by equipment and installation, certifications or listings should not be assumed. Check the markings on the individual breaker and the documentation for the equipment to be installed when a particular certification or compliance standard is required.

Where It Works Best

• The Q2M2100MT circuit breaker is best suited for existing and legacy electrical equipment that calls for a 100A, 2-pole Type Q2MT breaker with the same ratings and connection style. This is especially important in replacement work, where a breaker that looks similar may not necessarily have the correct dimensions or terminal arrangement.
