MPD2150RH - 50 Amp Circuit Breaker

MPD2150RH - 50 Amp Circuit Breaker

Replacing your breaker in older equipment usually comes down to one thing: does the replacement actually match what's already there? The manufacturer's product description identifies the MPD2150RH as a 150A, 2-pole, 120/240V MD-HTR circuit breaker with a 22K interrupt rating. It uses a thermal-magnetic trip and plug-in connection and is described as a reversible branch main breaker for electrical distribution equipment. Those details matter when you're trying to maintain the original form, fit, and function of a legacy installation.

Key Features and Benefits

• 150A product designation — The manufacturer's primary product description identifies the MPD2150RH as a 150A breaker.
• 2-pole configuration — Designed around the specified two-pole arrangement.
• 120/240V rating — Provides a clear voltage reference when checking compatibility with existing equipment.
• Thermal-magnetic trip — Uses the trip configuration identified in the manufacturer specifications.
• Plug-in connection — Connection style can be checked directly against the breaker being replaced.

Where It Works Best

The MPD2150RH makes the most sense when you're working with existing or legacy electrical equipment that specifically calls for this breaker configuration. Start by comparing the breaker being replaced with the MPD2150RH's 2-pole arrangement, 120/240V rating, MD-HTR designation, thermal-magnetic trip, plug-in connection, reversible branch main configuration, interrupt rating, and physical dimensions.
