The AIRPAX/SENSATA 209 series hydraulic magnetic circuit protectors offer a compact and reliable solution for branch circuit protection. Combining power switching with accurate protection, these breakers are suitable for a wide range of applications including EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, the 209 family adapts to local conditions, minimizing nuisance tripping. The inertial delay feature is standard for 50/60Hz units, providing protection against inrush currents from transformers, lamps, and capacitive filters. These protectors withstand high pulses without derating or sacrificing protection, making them a versatile choice for various industrial environments.
