MD150V - 150Amp Circuit Breaker

MD150V - 150Amp Circuit Breaker

With the MD150V, lug orientation is one detail worth checking closely before calling a replacement a match. This 150 amp, 2-pole Type MDV thermal magnetic circuit breaker is a plug-in main residential breaker rated 10k A.I.C. at 120/240VAC. That terminal arrangement matters when you're matching an existing or legacy installation, because amperage and pole count tell only part of the story.

Key Features and Benefits

• 150 Amp, 2-Pole Configuration: Clearly defined electrical ratings make it easier to compare the MD150V with the breaker being replaced.
• Type MDV: An important identifier when determining whether this breaker corresponds with existing equipment.
• Main Residential Application: The MD150V is specifically identified as a main residential circuit breaker.
• Plug-In Design: Its plug-in configuration is another key form-and-fit characteristic to confirm before installation.
• Thermal-Magnetic Circuit Breaker: Uses the thermal-magnetic configuration specified for this model.
• Staggered Lugs: This particular breaker has staggered lugs, making terminal layout an important part of the replacement check.
• Parallel Wire Entry: Wire enters the lug terminals parallel to the handle action, a useful physical detail for distinguishing the MD150V configuration.

Material Compliance and Certifications

The available specifications identify the staggered lug arrangement and state that the wire enters the lug terminals parallel to the handle action. No lug material, conductor range, terminal torque specification, or other terminal material information was supplied. Confirm those details separately when they are relevant to the installation.

The supplied specifications did not include specific UL, IEC, RoHS, REACH, or other certification and material-compliance information. No certification claims should therefore be assumed. Where a particular listing or compliance requirement applies, confirm it with appropriate documentation for the MD150V.

Where It Works Best

The MD150V 150 amp circuit breaker is best suited for compatible existing or legacy residential electrical equipment requiring a 2-pole, Type MDV plug-in main breaker with thermal-magnetic operation. The application should correspond with its 120/240VAC rating and 10k A.I.C. rating.

Pay particular attention to the terminals. The MD150V has staggered lugs, and the wire enters those lug terminals parallel to the handle's action. That physical configuration should be checked along with the 2.00" W x 7.06"L x 3.25"D dimensions rather than assuming fit from the 150A rating or MDV designation alone.
