219-3-39673-5 is a hydraulic magnetic circuit protector from the AIRPAX 209/219/229 series, designed for power switching combined with accurate, reliable circuit protection. The 219 series features a four-pole assembly specifically designed for three-phase operation, where three poles handle the circuit's operating current and overcurrent protection while the fourth pole enables remote shutdown via logic circuitry, interlocks, or manual remote control. The unit supports control voltages from 5 to 125Vdc or 5 to 240Vac and offers various terminal styles including screw terminals, stud, or solderless connectors with front or back connection options. Current ratings range from 10 to 100 amps with multiple delay curve options for different application requirements. Common applications include branch circuit protection for EDP equipment, air conditioners, panel boards, and lighting controls where remote shutdown capability is required.
