Airpax AP-12-638-3 Toggle Switch

The Airpax AP-12-638-3 Toggle Switch is a two-pole circuit protector from Airpax's AP12 family, designed for panel-mount operation and driven by a single toggle that actuates two independent series-trip protectors inside. It lists a 120/240 V AC rating and an 8.5 A operating current, with a frequency specification of 47/420 Hz and a 5-wire terminal configuration (SM-C-667918) for multi-point wiring. In AP12 devices, two independent series-trip protectors are actuated by one toggle, providing dual-circuit interruption, and the unit is designed for rugged panel mounting with a three-point mount and hardware such as 6-32 panel seal screws. Typical applications include power distribution panels, machine controls, and other equipment requiring reliable dual-circuit protection and a clearly identifiable ON/OFF control in a compact form factor.
