Allen-Bradley 1492-CB2 Molded Case Circuit Breaker

Allen-Bradley 1492-CB2 is a two-pole molded-case circuit breaker from the Bulletin 1492 family, engineered to protect motor circuits and general power distribution in industrial control panels by interrupting fault currents with a thermal-magnetic trip. The CB2 lineup is offered in multiple current ratings across variants such as 1492-CB2G015 (15 A) and 1492-CB-2-G-030 (30 A), as well as the 1492-CB2H100 (10 A), with voltage ratings up to 480 VAC and many listings specifying operation at 120/277/480 VAC. The 1492-CB2H100 variant is noted to provide up to 10 kA interrupting capacity at 480 VAC and is listed with bolt-on mounting in some configurations, illustrating the mounting options available within the family. For multi-pole installations, these breakers can be integrated with Rockwell Automation commoning accessories designed for the 1492 series, aiding the assembly of larger protection schemes in panels and motor control centers.
