The Littelfuse AL1-B0-34-610-321-C is a single-pole magnetic (hydraulic delay) circuit breaker designed for overcurrent protection in low-voltage AC circuits. It is rated for 10A continuous current at up to 277V. The hydraulic delay mechanism provides an inverse time-current characteristic, allowing brief inrush currents without nuisance tripping while still protecting against sustained overloads and short circuits.
This breaker features a rocker actuator for manual on/off control and is intended for panel mount installation. It is not illuminated. The compact single-pole design makes it suitable for branch circuit protection in distribution panels, industrial control equipment, and other applications requiring reliable overcurrent protection. The magnetic-hydraulic technology ensures stable operation across a wide temperature range without the need for external heating effects.
Available with a panel mount interface, the AL1-B0-34-610-321-C is a direct replacement for many standard single-pole breakers. It is important to verify compliance with applicable safety standards for the intended installation environment.
