Siemens Q280 Type QP Molded Case Circuit Breaker

Siemens Q280 Type QP molded-case circuit breaker is a two-pole, 80 A protective device for 120/240 VAC circuits, rated for 50/60 Hz operation and designed for plug-in mounting in Siemens QP-frame panels. It provides a 10 kA interrupt rating (AIC) at 120/240 VAC and uses a thermal-magnetic trip mechanism to guard against overloads and short circuits, making it suitable for protecting feeders and branch circuits in home and light commercial panels. This QP-series breaker is offered with different termination options in catalog listings, including INSTA-WIRE and load-lug configurations, and measures roughly 3 inches long by 3 inches wide by 2 inches high, a compact footprint that fits standard enclosure spaces while preserving space for other breakers in a panelboard.
