MPD2175RH - 75 Amp Circuit Breaker

MPD2175RH - 75 Amp Circuit Breaker

Finding the right breaker for existing or legacy electrical equipment is less about chasing newer technology and more about matching the specifications the system already requires. The MPD2175RH is a 2-pole, 120/240V reversible branch main circuit breaker identified in the manufacturer's product designation as a 175A, 22 kA, Type MD-HTR breaker. For maintenance teams working with legacy distribution equipment, the MPD2175RH gives you a clearly identifiable catalog number and set of electrical and physical characteristics to compare with the breaker being replaced. These breakers are built to last, but correct form, fit, and function still depend on matching the complete specification—not amperage, appearance, or part-number similarity alone.

Key Features and Benefits

• MPD2175RH catalog identification — Provides a specific part number for comparison with an existing breaker, equipment documentation, or maintenance records.
• 175A product designation — The manufacturer product title identifies the MPD2175RH as a 175-amp breaker; see the amperage discrepancy note below.
• 2-pole configuration — Designed around the two-pole arrangement specified for compatible electrical distribution equipment.
• 120/240V voltage rating — Gives installers and maintenance personnel a defined voltage specification to verify against the existing system.
• Thermal-magnetic trip operation — The detailed technical data identifies the trip range/type as thermal-magnetic.
• Plug-in connection — Connection style is identified as plug-in, providing another useful compatibility checkpoint.

Material Compliance and Certifications

The supplied technical information identifies the UL 489 standard for the MPD2175RH. This helps when checking the breaker against equipment and project requirements, but confirm any required listing or certification for the exact product being installed.

Where It Works Best

The MPD2175RH circuit breaker is relevant when servicing existing or legacy electrical distribution equipment that specifically calls for its two-pole, 120/240V operation, reversible branch-main configuration, thermal-magnetic trip characteristics, 22 kA interrupting capacity, plug-in connection, and corresponding MD-HTR form factor. Manufacturer information associates this breaker configuration with load-center main and feeder applications.
