The Cutler Hammer BR3100ST is a three-pole molded case circuit breaker designed to provide reliable overcurrent and short-circuit protection for three-phase industrial electrical systems. It features a 100A current rating and a 240V AC voltage rating, with a 10kA interrupting capacity at that voltage. The unit is constructed with a plug-in connection type, measures 4" x 3.5" x 4", and weighs 1.5 lb, utilizing a thermal-magnetic trip mechanism for both long-time and instantaneous protection. It complies with UL 489 and Federal Specification W-C375 standards and is rated for operation in temperatures from -25°C to 70°C (-13°F to 158°F). This breaker is typically applied in panelboards and switchboards for commercial and industrial power distribution, and includes a 120V shunt trip for remote tripping capability.
