Allen-Bradley 1492-SPM2B020 Miniature Circuit Breaker

Allen-Bradley 1492-SPM2B020 is a two-pole supplementary circuit breaker from the 1492-SPM family (Bulletin 1492-SPM) designed to provide additional overcurrent protection in electrical panels. It is rated at 2 A and features a Type B trip curve with no neutral terminal, intended for use alongside primary protection in 1492-SPM assemblies. The device is suitable for AC operation up to 480 V and DC operation up to 96 V, and it offers a short-circuit breaking capacity of 10 kA. As a supplementary protector, the 1492-SPM2B020 is used where an extra level of protection is desired for circuits, delivering reliable disconnection in fault conditions on a 2‑pole, 2‑wire configuration.
