AIRPAX / SENSATA 21946388147 Magnetic Circuit Protector

The Airpax/Sensata 209, 219, 229, and 249 series hydraulic magnetic circuit protectors combine power switching with reliable circuit protection. These breakers are ideal for branch circuit applications such as EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, they adapt to local environments and minimize nuisance tripping due to temperature variations. The 219 variant is specifically designed for manual controller applications and complies with UL Standard 508. The inertial delay feature provides protection against inrush currents from transformers and lamps.
