Siemens MP220AFC Afci 2 Pole 20 Amp Circuit Breaker

Product Description

The SIEMENS MP220AFC is an Arc Fault Circuit Interrupter (AFCI) circuit breaker designed for residential and light commercial electrical panels. It provides 20-amp, 2-pole protection with arc fault detection, which helps reduce the risk of electrical fires caused by damaged, arcing wiring. This breaker is part of the MP-AT2 series and is installed by licensed electricians during new construction, panel upgrades, or code-required AFCI retrofits. The dual-pole configuration makes it suitable for 240-volt branch circuits or paired 120-volt circuits requiring AFCI protection.

This breaker is used in residential electrical panels where AFCI protection is required by the National Electrical Code (NEC) for bedroom, living room, hallway, and other dwelling-unit circuits. It is commonly installed during panel changeouts, circuit additions, or code-compliance upgrades in single-family homes, multifamily units, and light commercial occupancies that follow NEC requirements for AFCI protection.

Key Features

• Arc Fault Circuit Interrupter (AFCI) technology detects and interrupts arcing faults to reduce fire risk
• 2-pole configuration for 240-volt or dual 120-volt branch circuit applications
• 20-amp rated current capacity
• MP-AT2 series design for compatible Siemens panel installations
• Meets NEC requirements for AFCI protection in applicable dwelling-unit circuits

Compatibility

Designed as an OEM-style replacement or new-install AFCI breaker for compatible Siemens MP-AT2 series loadcenters and electrical panels.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. Always de-energize the panel and verify the absence of voltage before handling any breaker or bus bar connection. Do not install in a panel that is not rated for MP-AT2 series breakers. AFCI breakers require proper neutral wire termination at the breaker terminal to function correctly.
