Cutler Hammer BWH2125 is a 2-pole molded case circuit breaker designed for overcurrent protection in commercial and industrial power distribution systems. This 125A unit operates at 240V AC with a 25kA interrupting capacity, utilizing a thermal magnetic trip mechanism for long-time and instantaneous fault response. The bolt-on breaker measures 6.25 inches deep by 5.25 inches high by 5.25 inches wide, weighs 2.75 lb, and accepts wire sizes from #2 AWG to 300 kcmil copper or aluminum. It is UL 489 listed and meets Federal Specifications Classification W-C375, with an operating temperature range of -13°F to 158°F (-25°C to 70°C). This single-phase breaker is suitable for panelboard installations requiring reliable short-circuit and overload protection in industrial motor control centers, lighting panels, and distribution boards.
