Westinghouse Electric KB2250F-HKB100T Breaker Frame

The Westinghouse KB2250F-HKB100T Breaker Frame is a fixed-mount, 2-pole protection frame designed for industrial and commercial distribution systems to provide overcurrent and short-circuit protection for high-capacity circuits in switchgear, panelboards, and motor control centers. It uses the HKB100T trip unit with a 100 Amp trip rating within a 225 Amp frame, rated for 600 V AC with an interrupt rating of 14 kA, and employs a thermal-magnetic trip type for reliable fault interruption. This frame is intended for commercial and industrial electrical protection systems and installation in panel-mounted configurations. Common replacements include Eaton KB2250F, Cutler-Hammer HKB100T, and Square D KA26100.
