The AIRPAX/SENSATA 209 series hydraulic magnetic circuit protectors offer a robust solution for branch circuit protection. These breakers combine power switching with accurate and reliable protection in a compact, single or multi-pole unit, making them suitable for applications like EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, the 209 family adapts to various environments, minimizing nuisance tripping due to temperature variations. The inertial delay feature handles inrush currents effectively, and the breakers withstand high pulses without affecting normal delay curves. Available with various terminal styles and configurations, the 209 series provides a versatile solution for diverse industrial needs.
