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, making them suitable for applications like EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, these protectors adapt to local conditions and minimize nuisance tripping due to temperature variations. They are designed to withstand high pulses without affecting normal delay curves, ensuring consistent protection.
