Siemens Q280 - 80 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

The Siemens Q280—an 80A, 240V, 2-pole plug-in molded case circuit breaker—delivers dependable branch circuit overcurrent and short-circuit protection for panelboards and load centers. Engineered for fast, hassle-free installations, it’s a smart choice for both new builds and panel upgrades where reliability matters.

• Fast plug-in connection — streamline installation and replacement, reducing panel downtime and enabling swift serviceability.
• Thermal-magnetic trip unit — provides stable, repeatable protection by responding to sustained overcurrent (thermal) and instantaneous short circuits (magnetic), helping protect wiring and connected equipment.
• 2-pole, 240V operation — ensures simultaneous disconnection of both live conductors for enhanced safety on multi-wire branch circuits.
• OEM-compatible design — specifically tuned to work with matching Siemens Q-series panelboards and other compatible load centers, ensuring reliable performance when paired correctly.
• Versatile for multiple sectors — well suited for residential, commercial, and light industrial electrical distributions, from home service panels to small business equipment rooms.

Why this matters — choosing a plug-in molded case circuit breaker like the Q280 means faster service turns, fewer tools required on-site, and dependable protection that aligns with standard Siemens panelboard configurations. The 80A rating suits mid-range branch circuits and feeders, delivering robust protection without unnecessary nuisance tripping when loads are balanced and properly wired.

Ideal use cases — upgrading an aging panel, adding a new subpanel for a workshop or garage, or replacing a failed breaker in a Siemens-compatible load center. It’s designed to snap into place in compatible enclosures, with a clear indication of trip status to simplify diagnostics during maintenance.

For best results, confirm panel compatibility with your Siemens load center labeling, ensure correct slot placement for a secure plug-in connection, and reset after a trip only once the fault is resolved. With the Siemens Q280, you gain a compact, reliable, and rapid-protection solution that keeps your electrical system safe and compliant.
