MD175V - 175A Circuit Breaker

MD175V - 175A Circuit Breaker

When you're matching a main residential breaker to existing equipment, details like lug orientation can matter as much as the amp rating. The MD175V is a 175-amp, 2-pole Type MDV thermal magnetic circuit breaker with a plug-in configuration and a 10k A.I.C. rating at 120/240VAC. When the MDV type, 175A rating, two-pole configuration, 120/240VAC rating, interrupting capacity, plug-in design, lug arrangement, wire-entry orientation, and physical dimensions match the application, the MD175V can be considered a form, fit, and functional replacement candidate for compatible existing or legacy residential equipment.

Key Features and Benefits

• 175 Amp, 2-Pole Configuration: Provides two key specifications for direct comparison with the breaker being replaced.
• Type MDV: The MDV designation is an important part of identifying the correct breaker configuration.
• Main Residential Application: This model is specifically identified as a main residential circuit breaker.
• Plug-In Design: The supplied plug-in configuration should match the requirements of the existing electrical equipment.
• Thermal-Magnetic Circuit Breaker: Uses the thermal-magnetic trip configuration specified for the MD175V.
• Staggered Lugs: The staggered lug arrangement is a significant physical detail when evaluating replacement compatibility.
• Parallel Wire Entry: Wire enters the lug terminals parallel to the handle, an especially useful detail for distinguishing this model from breakers with a different conductor-entry orientation.

Material Compliance and Certifications

The available specifications identify the MD175V as having staggered lugs, with wire entering the lug terminals parallel to the handle action. The supplier did not provide the exact lug material, conductor range, terminal torque requirements, or other connection specifications. Confirm those details separately when they are needed for installation.

The supplier did not provide specific UL, IEC, RoHS, REACH, or other material-compliance or certification information for the MD175V. Rather than assuming a listing or compliance status, verify any applicable requirement using appropriate product documentation.

Where It Works Best

The MD175V 175 amp circuit breaker is best considered for compatible existing or legacy residential electrical equipment that requires a 2-pole, Type MDV plug-in main circuit breaker with thermal-magnetic operation. A prospective replacement should match the specified 120/240VAC rating, 10k A.I.C. rating, and 175A amperage.

This model's physical configuration deserves particular attention. The MD175V has staggered lugs, with wire entering the lug terminals parallel to the handle's action. That wire-entry direction should not be treated as a minor detail when determining form and fit. The 2.00 "W x 7.06 "L x 3.25 "D dimensions should also be compared with the existing breaker and available installation space.
