Siemens B220AFC 20A 2P Circuit Breaker, AFCI, Bolt-On | AmpState

Meet the Siemens B220AFC — a 20A, 2-pole AFCI circuit breaker designed to protect your electrical distribution with precision and reliability. Built for panelboards and load centers, this bolt-on breaker delivers arc-fault protection where it matters most, helping to safeguard both your system and occupants.

Key benefits

• AFCI protection detects dangerous arc faults and interrupts power, reducing the risk of electrical fires in living and working spaces.
• 2-pole, 20-amp design suited for circuits that require both hot legs to be protected together, delivering balanced protection for multiwire branch circuits.
• Bolt-On installation simplifies replacement and upgrades in compatible Siemens panelboards and load centers, minimizing downtime.
• Direct part-number match is ideal for maintenance teams, panel builders, and spare inventory where precise compatibility matters.
• Trusted Siemens quality backed by a long-standing reputation in electrical distribution components.

Who this is for

• Maintenance teams maintaining Siemens panelboards and load centers who need a reliable AFCI bolt-on replacement.
• Panel builders compiling ready-to-install parts for field service and new installations.
• Spare inventory planners who require a precise part number (B220AFC) to avoid mismatches in the field.

Practical use cases

• Protect circuits in living spaces such as bedrooms and family rooms where arc-fault protection is often required by code.
• Replace a legacy non-AFCI breaker to upgrade safety on shared multiwire branches in residential or light commercial layouts.
• Stock for quick replacements in service vans or electrical rooms where fast, accurate part matching saves time.

Installation, compatibility, and tips

The Siemens B220AFC is designed for panelboards and load centers that support bolt-on, 2-pole AFCI protection. Before installation, confirm that your enclosure is compatible with Siemens B-series bolt-on breakers and that the circuit demands 20A protection on two poles. When in doubt, verify fit and listing with AmpState’s support team to ensure a direct part-number match and code-compliant installation.
