The 209 Series is ideal for branch circuit applications such as EDP, air conditioners, panel boards and lighting controls. The 209 is actually a family of circuit breakers available in one through six pole assemblies with a variety of configurations and terminal styles to meet your application needs. Utilizing the hydraulic-magnetic principle, the 209 Series products adapt to local applications and environments.

The Airpax™ AP series magnetic circuit protector is available in either DC, 50/60Hz or 400Hz versions and with various delays to match the protector to specific application requirements. Unlike a thermal circuit protector, the AP does not change its trip current over a wide temperature span. One of the most important features of this protector is the “trip free” action, meaning the circuit will not remain closed in the presence of an overload, even though the handle is held in the ON position.
