Allen-Bradley 1492-CB2H030 is a two-pole energy-limiting miniature circuit breaker from the 1492-CB family, designed for DIN-rail mounting in industrial control panels. It is rated at 3 A and is used to protect circuits feeding small motors or control circuitry in automation systems. Some listings describe this model as suitable for loads up to about 1/3 HP, reflecting its role in compact motor applications. The unit provides two poles for simultaneous protection of both conductors in the circuit, making it a compact choice for panel spaces where coordinated overcurrent protection is required.
