Siemens Q220AFCCSA - 20 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

Siemens Q220AFCCSA is a 20A, 240V, 2-pole plug-in molded case circuit breaker designed to protect individual branch circuits from overcurrent and short-circuit events in panelboards and loadcenters. The plug-in design simplifies installation or replacement, reducing downtime during panel upgrades or service calls.

Why this breaker stands out

• Plug-in convenience: Fast connection that minimizes labor time during installation or replacement in compatible Siemens panelboards and loadcenters.
• Thermal-magnetic protection: Combines a thermal overload element with a magnetic trip for prompt, repeatable response to overloads and short circuits.
• Specifically rated: 20A, 240V, 2-pole configuration designed for branch circuits feeding lighting, outlets, and modest motor loads in residential, commercial, and light industrial settings.
• OEM compatibility: Engineered to work with Siemens OEM load centers to maintain warranty and coordination across the electrical system.

Ideal use cases

• Home electrical panels expanding circuits for kitchens, HVAC, or workshop outlets where a reliable 20A protection is needed.
• Small offices or retail spaces upgrading panels or replacing failing breakers with a like-for-like Siemens solution.
• Light industrial applications where robust plug-in protection matches standard panel components.

How it works

The breaker automatically interrupts current when a fault is detected. The thermal element responds to sustained overloads, while the magnetic element trips rapidly during sharp, high-current faults, preventing damage to wiring and connected equipment.
