Q2M3175MB - 175 Amp Circuit Breaker

Need to match a Q2M3175MB circuit breaker in an existing electrical system? Start with the details that matter most: ratings, dimensions, connections, and breaker type. The Q2M3175MB is a 175-amp, 3-pole thermal-magnetic circuit breaker rated at 10 kAIC at 240 VAC. It is a Type Q2MB breaker with a non-interchangeable trip unit. On the connection side, you'll find 1/4-20" studs on the line side and lug terminals on the load side. The breaker measures 6.5 inches high, 4.5 inches wide, and 3.13 inches deep. That combination of specifications makes it suitable for compatible legacy electrical equipment where the replacement needs to closely match the original breaker in form, fit, and function. Its thermal magnetic design provides overload and short-circuit protection within the stated ratings. For maintenance teams and electricians working with older equipment, having the correct physical and electrical configuration can make all the difference.

Key Features and Benefits

  • 175 amp rating for applications designed around this current rating.
  • Three-pole configuration for compatible three-pole electrical systems.
  • Thermal-magnetic operation provides overload and short-circuit protection.
  • Rated 10k AIC at 240VAC.
  • Type Q2MB construction for equipment requiring this specific breaker configuration.
  • The non-interchangeable trip unit maintains the breaker's fixed trip arrangement.
  • 1/4-20" line-side studs and load-side lug terminals provide the required connection setup.
  • Compact, defined dimensions help when matching the breaker to existing legacy equipment.
  • Built for lasting service when used within the proper application and ratings.

Material Compliance and Certifications

  • Certification and material-compliance information is not included in the available specifications for this breaker. If your facility or application requires a particular agency listing or compliance standard, check the product markings and supporting documentation before installation. Certifications such as UL, CSA, or RoHS should only be considered applicable when specifically confirmed for the individual breaker.

Where It Works Best

  • The Q2M3175MB makes sense for maintenance and replacement applications in compatible legacy electrical systems where the existing equipment calls for this particular breaker configuration. It's especially important to consider the complete set of specifications rather than simply matching the 175 amp rating.
