Cutler Hammer CHB2125 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial and commercial electrical systems. It features a 125A current rating and a 240V AC voltage rating, housed within a compact, bolt-on configuration measuring 3.6" x 3.4" x 1.5" (LxHxW) and weighing 0.6 lb. This two-pole, single-phase breaker is UL 489 listed and employs a thermal-magnetic trip mechanism with long-time and instantaneous (LI) functions for coordinated protection, capable of interrupting up to 10kA at 240V. Its robust construction supports wire sizes from AWG 4 to 1/0 and operates reliably across a temperature range of -25°C to 70°C (-13°F to 158°F), making it suitable for panelboards, switchboards, and industrial control panels.
