Siemens B280 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in single-phase electrical systems. It features a thermal-magnetic trip mechanism with long-time and instantaneous (LI) functions, rated for 80A continuous current and 120/240V AC voltage within a 125A frame. The compact, bolt-on unit measures 2.563" x 2.00" x 3.122" (65.1mm x 50.8mm x 79.3mm), weighs 0.639 lb, and is constructed with lug terminals compatible with wire sizes from 12 AWG (Al) or 14 AWG (Cu) minimum to 10 AWG maximum. It complies with key industry standards including UL listing, CSA certification, HACR rating, and NOM certification, and is typically applied in Siemens P1 panelboards for commercial and light industrial distribution.
