MP120AF - 20 Amp Circuit Breaker

MP120AF - 20 Amp Circuit Breaker

The MP120AF is a 1-pole, 120VAC plug-in thermal-magnetic circuit breaker with arc-fault circuit interruption, built around the MP-AF configuration. When you're matching a breaker for existing electrical equipment, the catalog number alone isn't enough—the pole count, voltage, interrupting rating, connection style, dimensions, and protection type all matter. One important point deserves attention: the supplied specifications list the amperage as 0A.

Key Features and Benefits

• Arc Fault Circuit Interruption: The MP120AF is identified as a circuit breaker with arc fault circuit interruption, an important feature when matching an existing breaker.
• Thermal-Magnetic Trip: Uses the specified thermal-magnetic trip design.
• Single-Pole Configuration: The 1-pole design provides a clear compatibility point when checking an existing installation.
• Plug-In Design: The stated plug-in configuration is another key form-and-fit characteristic to confirm with the equipment.
• MP-AF Type: Matching the MP-AF type helps narrow down compatibility beyond amperage and voltage alone.
• 40°C Rated: The breaker carries the specified 40°C rating.

Material Compliance and Certifications

The supplied specifications identify the MP120AF as HACR Rated. No UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification information was provided for this part number, so do not assume those designations.

Where It Works Best

The MP120AF arc fault circuit breaker is most appropriately evaluated for compatible existing or legacy electrical equipment requiring its specific MP-AF type, 1-pole configuration, plug-in connection, 120VAC rating, 10k interrupting rating, thermal-magnetic trip, and arc fault circuit interruption. Also check the stated dimensions carefully, because electrical ratings alone don't establish physical compatibility.
