MDT175 - 175 Amp Circuit Breaker

MDT175 - 175 Amp Circuit Breaker

When you're replacing a residential main breaker, the catalog number alone isn't enough—the electrical ratings, physical size, connection style, and required panel space must all match. The MDT175 is a 175 amp, 2-pole MD-T thermal magnetic circuit breaker with a plug-in configuration for compatible residential main applications. For legacy equipment with these same specifications, the MDT175 can serve as a form, fit, and functional replacement candidate when all application requirements match. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 175 Amp Rating: Provides the specified 175A rating for compatible residential main applications.
• 2-Pole Configuration: Matches equipment requiring a two-pole MD-T breaker.
• 120/240VAC Operation: Rated specifically for 120/240VAC applications.
• Thermal-Magnetic Trip: Uses the specified thermal-magnetic trip configuration.
• Plug-In Design: The plug-in configuration is an important form-and-fit detail when identifying a suitable replacement.
• Four Panel Spaces Required: The MDT175 requires four panel spaces, so confirm available panel space before installation.
• 40°C, 50/60Hz Rating: Temperature and frequency specifications are clearly identified for application matching.
• HACR Type: The supplied product information identifies this breaker as HACR Type.

Where It Works Best

The MDT175 175 amp circuit breaker is best considered for compatible existing or legacy residential electrical equipment that specifically requires an MD-T, 175A, 2-pole, plug-in residential main thermal magnetic circuit breaker. A proper match should account for the 120/240VAC rating, 10k A.I.C., 50/60Hz frequency, 40°C rating, HACR Type designation, four-panel-space requirement, and physical dimensions.
