Siemens QE220 - 20 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

The Siemens QE220 is a 2-pole, plug-in molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection right where you need it—in panelboards and load centers. Built for fast, secure installations, this 20 A, 240 V device is a smart choice for residential, commercial, and light industrial applications that demand reliable circuit protection with minimal downtime.

• Fast plug-in connection for quick installation and easy replacement, reducing service time during panel upgrades or circuit servicing.
• Thermal-magnetic trip unit delivers stable, repeatable protection by handling overloads thermally and short circuits magnetically, helping to prevent nuisance trips and protect wiring and devices.
• 2-pole, 240 V design provides simultaneous disconnection of both hot conductors, enhancing safety for shared neutral circuits and multi-wire branch circuits.
• OEM-compatible—designed to pair with matching Siemens OEM load centers and panelboards for consistent fit, performance, and coordination with existing protection schemes.
• Versatile application ideal for residential service panels, small commercial installations, and light industrial distribution where reliable protection and fast maintenance matter.

What it protects and how it helps

The QE220 protects branch circuits from overcurrent and short circuits, reducing the risk of wiring damage, equipment failure, and fire hazards. Its thermal-magnetic trip mechanism acts quickly on short circuits while maintaining stable protection during normal fluctuations in current, so you don’t experience unnecessary interruptions.

Ideal use scenarios

• Upgrading a home panel to support critical circuits with quick, reliable replacement in Siemens-compatible systems.
• Installing in small commercial panels for feeders and branch circuits that require prompt interruption during faults.
• Retrofits and service upgrades where downtime needs to be minimized and compatibility with existing Siemens equipment is a priority.
