The CA1-B0-24-620-321-C is a single-pole circuit breaker manufactured by Littelfuse Inc. Designed for electrical circuit protection, this device interrupts current flow when overload or short-circuit conditions are detected. It operates at a continuous current rating of 20 amperes and supports a maximum voltage rating of 480 volts. The unit utilizes a magnetic hydraulic delay trip mechanism to provide reliable protection against sustained overcurrents while tolerating brief inrush currents typical in industrial loads.
Mechanical specifications include a lever-style actuator for manual switching and panel mounting configuration. The breaker does not feature integrated illumination. It carries multiple international approval certifications, including UL, CSA, and CCC, ensuring compliance with safety standards across various global markets.
Engineers integrating this component into control panels or power distribution systems should account for its single-pole architecture and direct panel installation requirements. The magnetic hydraulic delay characteristic makes it suitable for applications requiring coordination with downstream protective devices without nuisance tripping during startup transients.
The CA1-B0-24-620-321-C circuit breaker has a maximum voltage rating of 480 volts.
This model contains a single pole for circuit interruption.
The device uses a manual lever actuator for switching.
