MP120GF - 20 Amp Circuit Breaker

MP120GF - 20 Amp Circuit Breaker

When you're replacing a 20 amp GFCI circuit breaker, getting the details right matters far more than simply matching the amperage. The MP120GF is a 20A, 1-pole, 120VAC plug-on circuit breaker identified as Type MP-GT / MP-HGT, Class A, with 5mA ground-fault personnel protection and a 10k interrupting rating. For replacement work in compatible existing or legacy equipment, the important checks include the MP120GF catalog number, 20A continuous current rating, single-pole configuration, 120VAC rating, 5mA trip level, plug-on configuration, and equipment compatibility. Its solid construction is built to last when the breaker is correctly selected, installed, operated, and maintained for its intended application.

Key Features and Benefits

• Class A GFCI Protection: The MP120GF provides the specified 5mA ground-fault protection for personnel, an important functional requirement when replacing an existing GFCI breaker.
• 20 Amp, Single-Pole Configuration: Rated at 20A continuous current with a 1-pole design for applications requiring these exact electrical characteristics.
• 120VAC Rating: Designed for 120VAC, 50/60Hz operation.
• Plug-On Configuration: The plug-on design is an important physical compatibility characteristic to check when matching existing equipment.
• MP-GT / MP-HGT, Class A Design: These manufacturer-specified type designations provide additional information for identifying the correct form, fit, and function.
• SWD Application: Specifically identified for frequent-switching applications involving 120VAC fluorescent lighting.
