Q2M3110MB - 100 Amp Circuit Breaker

Q2M3110MB - 100 Amp Circuit Breaker

Finding the right replacement breaker often comes down to the details, and the Q2M3110MB has a very specific set of them. This 3-pole, 110-amp thermal-magnetic circuit breaker is a Q2MB type, rated at 10 kAIC at 240 VAC. It uses a non-interchangeable trip unit and has 1/4-20" studs on the line side with lug terminals on the load side. Physically, the breaker measures 6.5" high, 4.5" wide, and 3.13" deep. Those specifications are especially important when you're working with existing or legacy electrical equipment where the replacement needs to match the original breaker's form, fit, and function. Rather than relying on amperage alone, compare the Q2M3110MB part number, dimensions, pole configuration, voltage, interrupting rating, trip type, and terminal arrangement with your existing equipment. It's a straightforward, built-to-last circuit breaker for compatible applications that require this particular configuration.

Key Features and Benefits

• 110-amp, 3-pole breaker for equipment designed around this specific electrical configuration.
• Thermal-magnetic operation provides overcurrent and short-circuit protection within the breaker's stated ratings.
• 10k AIC at 240VAC interrupting rating.
• Q2MB type for applications requiring this breaker configuration.
• Features a non-interchangeable trip unit.
• 1/4-20" studs on the line side help match the connection arrangement found in compatible installations.
• Lug terminals on the load side provide the specified load connection.
• At 6.5" x 4.5" x 3.13", its dimensions can be checked directly against the breaker being replaced.
• A practical fit for legacy equipment maintenance and replacement when the original specifications call for the Q2M3110MB configuration.

Material Compliance and Certifications

• Certification and material-compliance information is not included in the available specifications for the Q2M3110MB. Because of that, specific claims regarding UL listing, RoHS compliance, or other certifications should not be assumed. If your facility or application requires a particular certification, check the markings on the breaker and any available supporting documentation before installation.

Where It Works Best

• The Q2M3110MB is best suited to repair and maintenance work involving compatible legacy electrical systems. It's a particularly relevant replacement when the existing application calls for a 110A, 3-pole Q2MB thermal-magnetic circuit breaker with a 10k AIC rating at 240VAC.
  
  And with older electrical equipment, the small details count. Check the terminal arrangement and the electrical ratings. The Q2M3110MB uses 1/4-20" studs on the line side and lug terminals on the load side. Dimensions should also be confirmed against the existing installation.
