MP250GF - 50 Amp Circuit Breaker

MP250GF - 50 Amp Circuit Breaker

When you're replacing a breaker in an existing load center, the catalog number matters—but so do the electrical ratings and breaker configuration behind it. The MP250GF is a 50-amp, 2-pole Type MP-GT GFCI circuit breaker rated for 120/240V with a 10 kA interrupting rating. For existing or legacy equipment calling for the MP250GF, these details matter when evaluating form, fit, and functional replacement. These breakers are built to last, but proper compatibility still comes first: confirm the MP250GF catalog number, 50A amperage, two-pole configuration, 120/240V rating, 10 kA interrupting rating, MP-GT type, Class A GFCI requirements, and plug-on configuration against the equipment specifications before installation.

Key Features and Benefits

• 50A current rating: Matches applications and existing equipment specifically requiring a 50-amp circuit breaker.
• 2-pole configuration: Designed around the specified two-pole arrangement.
• 120/240V rating: Meets the stated voltage requirement for compatibility with the existing electrical system.
• Class A GFCI personnel protection: Includes the manufacturer-specified ground-fault circuit-interrupter function for personnel protection.
• 5 mA trip range: Provides the stated GFCI trip characteristic for this model.
• Plug-on configuration: An important form-and-fit detail when matching the MP250GF to compatible existing equipment.

Material Compliance and Certifications

The manufacturer identifies the MP250GF as UL Listed, CSA Certified, and HACR Rated. These specifications help confirm the breaker against equipment, code, or project requirements.

Where It Works Best

The MP250GF is intended for existing or legacy electrical equipment that specifically calls for a 50A, 2-pole, 120/240V Type MP-GT Class A GFCI circuit breaker with a 10 kA interrupting rating and plug-on configuration. This is especially important with replacement breakers: matching the amperage while overlooking the breaker type, pole arrangement, voltage, interrupting capacity, GFCI characteristics, or physical connection method can result in the wrong part for the equipment.
