The Littelfuse AF1-B2-34-420-1F9-A is a 1-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in electrical circuits. It is rated for 2A continuous current and 277V AC supply voltage. The magnetic hydraulic delay mechanism provides precise time-current characteristics, allowing for short-circuit protection while accommodating inrush currents. This breaker features a rocker actuator for manual switching and reset, and is non-illuminated. It is mounted via panel mount snap-in, simplifying installation into enclosures or panels. The breaker is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited). It is suitable for use in commercial and industrial applications requiring reliable circuit protection. The 1-pole design is ideal for single-phase AC circuits, and the hydraulic delay provides time delay for motor starting or other transient currents.
