... AP/UP, AP/MIL Series - Multi-Pole The AP12 consists of two independent series trip protectors, each available with its own rating and delay characteristics. This two pole unit can therefore have an unlimited number of combinations, which makes ordering by a code system impractical. Thus, if the poles differ, a descriptive drawing is recommended ...

... DC circuit. It has a short time delay and a rating of 20 amperes. The coding given permits a descriptive part number, with limitations. In the illustrated double pole example (AP12-1- 51-203 automatically assumed that both poles are identical. One great virtue of magnetic circuit protectors is their adaptability to complex circuits, thus variations from pole to pole become the rule rather than the exception ...
