The Airpax/Sensata 209, 219, and 229 series hydraulic magnetic circuit protectors combine power switching with accurate and reliable circuit protection. These circuit 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 applications and environments, minimizing nuisance tripping due to temperature variations. The 209 family can withstand high pulses without tripping and offers unique inertial delay for inrush currents. Available in various configurations and terminal styles.
