The AIRPAX / SENSATA 209, 219, 229, and 249 series hydraulic magnetic circuit protectors offer a versatile 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 environments and minimize nuisance tripping due to temperature variations. They are designed to withstand high pulses without derating or sacrificing protection, making them suitable for a wide range of industrial and commercial applications.
