The Littelfuse AA1-B0-34-640-MB2-C is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in electrical circuits. It is rated for 40A continuous current and can interrupt voltages up to 277V AC and 80V DC. The magnetic hydraulic delay mechanism provides precise, temperature-stable tripping characteristics, making it suitable for applications where nuisance tripping must be minimized.
The breaker features a compact 1-pole form factor and is built for reliable performance in demanding environments. Its robust construction ensures long service life in industrial, commercial, and transportation applications. The hydraulic delay allows for momentary inrush currents without tripping, while still providing fast response to sustained overloads.
