The Airpax SNAPAK series is a snap-acting hydraulic magnetic circuit protector designed to combine power switching and accurate, reliable circuit protection in a single, aesthetically pleasing package. This innovative design replaces three separate components – a power switch, a fuse, and a fuse holder – simplifying assembly, reducing inventory, and increasing panel density. The SNAPAK is suitable for both DC and 50/60Hz applications, and 400Hz units are also available. Its snap-acting mechanism ensures immediate opening and closing of contacts, preventing operator interference and minimizing arcing. Typical applications include office appliances, electronic data processing, medical equipment, and vending machines. Available in SPST and DPST configurations, the SNAPAK offers versatility for various applications requiring current sensing and breaking.
