Q2M3175MT - 175 Amp Circuit Breaker

Q2M3175MT - 175 Amp Circuit Breaker

If you're replacing a breaker in an existing electrical system, the little details matter just as much as the amp rating. The Q2M3175MT is a 175A, 3-pole thermal-magnetic circuit breaker in the Q2MT series, rated 10 kA.I.C. at 240VAC. It has a non-interchangeable trip unit, with lug terminals on the line side and 1/4-20" studs on the load side. That terminal arrangement is an important detail to check when matching this breaker to existing equipment. The Q2M3175MT measures 6.5 inches high, 4.5 inches wide, and 3.13 inches deep, so you'll also want to compare its physical dimensions with those of the breaker being replaced. For maintenance work involving compatible legacy electrical equipment, this breaker provides a specific combination of size, amperage, pole configuration, interrupting rating, and connections. It's built to last when used for the application for which it was designed and installed, in accordance with the equipment's requirements.

Key Features and Benefits

• 175A, 3-pole configuration for electrical equipment designed around these ratings.
• Thermal-magnetic trip operation provides the breaker's specified circuit protection function.
• Rated 10k A.I.C. at 240VAC.
• The non-interchangeable trip unit is part of the Q2M3175MT configuration.
• Line-side lug terminals provide the specified incoming connection.
• 1/4-20" load-side studs make the connection arrangement easy to identify when checking an existing installation.
• 6.5" x 4.5" x 3.13" footprint provides clear dimensions for checking form and fit.
• Well suited to legacy equipment maintenance and replacement when the existing application calls for the same specifications.

Material Compliance and Certifications

• No specific material-compliance or certification information was included in the available specifications for the Q2M3175MT. If your application requires a particular UL, CSA, RoHS, or other certification or compliance standard, check the markings and documentation for the individual breaker before installation. This avoids making assumptions based solely on the part number or breaker type.

Where It Works Best

• The Q2M3175MT circuit breaker is a good fit for maintenance and replacement work on compatible legacy electrical systems that require a 175-amp, 3-pole Q2MT thermal-magnetic breaker with a 10kA I.C. rating at 240VAC.
