The Littelfuse AA1-B0-22-440-1D2-D is a magnetic hydraulic delay circuit breaker designed for overcurrent protection. It is rated for 4A at 250V and features a single-pole configuration. The breaker uses a hydraulic delay mechanism to provide stable trip characteristics over a wide temperature range, making it suitable for applications where nuisance tripping must be minimized.
The circuit breaker is panel mounted with a lever actuator for manual reset. It has a compact design ideal for industrial control panels, power distribution systems, and machinery. The RoHS3 compliant construction ensures environmental regulatory compliance. The breaker is unilluminated and operates without additional illumination components.
