Q2M2175MB - 175 Amp Circuit Breaker

Q2M2175MB - 175 Amp Circuit Breaker

Need to match a Q2M2175MB circuit breaker in an existing electrical system? Start with the details that matter most. This 175-amp, 2-pole thermal-magnetic circuit breaker is a Q2MB type, rated 10 kA I.C. at 120/240 VAC. It has a non-interchangeable trip unit, with 1/4-20" studs on the line side and lug terminals on the load side. Those connection details are worth checking closely, especially when you're working with older electrical equipment where the right fit involves more than simply matching the amp rating. At 6.5" high, 3.0" wide, and 3.13" deep, the Q2M2175MB has clearly defined dimensions that can be compared with the breaker already installed. For maintenance and replacement work, it offers the familiar form, fit, and function needed in compatible legacy equipment. It's a practical, straightforward circuit breaker built to last when used in its intended application.

Key Features and Benefits

Material Compliance and Certifications

• Specific material compliance information and certification details were not included in the available specifications for the Q2M2175MB. Any required agency listings, material declarations, or compliance markings should therefore be confirmed on the individual breaker or its supporting documentation rather than assumed.
• As with any replacement circuit breaker, check the equipment requirements and applicable electrical codes before installation.
  

Where It Works Best

• The Q2M2175MB 175A circuit breaker is best suited to maintenance and replacement applications involving compatible legacy electrical equipment. It is particularly relevant when the existing setup requires a Q2MB-type breaker with 2 poles, a 175-amp rating, 120/240 VAC operation, and a 10 kA I.C. rating.
