The AIRPAX / SENSATA 209, 219, and 229 series hydraulic magnetic circuit protectors offer a robust solution for branch circuit protection. These circuit breakers combine power switching with accurate and reliable protection in a compact, single or multi-pole unit, ideal for applications like EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, these protectors adapt to local conditions, minimizing nuisance tripping due to temperature variations and withstanding high pulses without affecting normal delay curves. Available in various configurations and terminal styles, they provide a versatile solution for diverse industrial needs.
