Cutler-Hammer has two pole Arc Fault breakers available. We have independent trip and common trip. Common trip meet the requirements of 210-4 for multiwire circuits on the same yoke. The independent trip can be used on home run circuits. The date on the website was a mis-print. It should have read November of 2001. The web page has been updated, and you can find the cat numbers at http://www.ch.cutler-hammer.com/NAS...8&Sec=products&uid=Variables.uid
