AIRPAX / SENSATA 21937268184 Magnetic Circuit Protector

The AIRPAX/SENSATA 209/219/229/249/279 series hydraulic magnetic circuit protectors combine power switching with reliable circuit protection in a compact, single or multi-pole unit. Designed for branch circuit applications such as EDP, air conditioners, panel boards, and lighting controls, these protectors utilize the hydraulic-magnetic principle to adapt to local conditions and minimize nuisance tripping due to temperature variations. The inertial delay feature is standard for 50/60Hz units, providing protection against inrush currents from transformers, lamps, and capacitive filters. Available with various terminal styles and configurations, these circuit protectors offer versatility for a wide range of industrial applications.
