MDT150 - 150 Amp Circuit Breaker

MDT150 - 150 Amp Circuit Breaker

The MDT150 is a 150 amp, 2-pole MD-T thermal magnetic circuit breaker for your compatible residential equipment that requires a plug-in main breaker and four panel spaces. Its electrical specifications are straightforward: 120/240VAC, a 10 kA AIC rating, 50/60Hz frequency, and a 40°C rating. When the MD-T type, 150A rating, two-pole configuration, electrical ratings, four-space requirement, and dimensions all match the application, the MDT150 can be considered a form, fit, and functional replacement candidate. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 150 Amp Residential Main: Rated at 150A and specifically identified for residential main applications.
• 2-Pole Configuration: Provides the supplied two-pole configuration for compatible 120/240VAC equipment.
• Thermal Magnetic Trip: The MDT150 is specifically identified as a thermal magnetic trip circuit breaker.
• Plug-In Design: Its plug-in configuration is an important compatibility point when matching an existing breaker.
• Requires Four Panel Spaces: This is a key physical-fit requirement and should be confirmed before selecting the breaker.
• 40°C and 50/60Hz Ratings: Both values are provided for a more complete application match.
• HACR Type: The supplied product information identifies this circuit breaker as HACR Type.

Material Compliance and Certifications

The supplied specifications identify the MDT150 as HACR Type. No specific UL, IEC, RoHS, REACH, or other material-compliance or certification information was provided for this exact catalog number, so do not infer those qualifications from similar breakers.

Where It Works Best

The MDT150 150 amp circuit breaker suits compatible existing and legacy residential electrical equipment that calls for an MD-T, 2-pole, 150A, 120/240VAC plug-in residential main thermal magnetic breaker. The application should also match its 10 kA.I.C. rating, 50/60Hz frequency, 40°C rating, HACR Type designation, and four-panel-space requirement.

For replacement work, don't stop at the amperage. The 2.0"W x 6.44"H x 2.38"D dimensions, MD-T type, plug-in configuration, pole count, electrical ratings, and required panel space should all agree with the existing equipment. Lug or terminal material, conductor range, and terminal torque specifications were not supplied and should be verified separately where required.
