The Airpax/Sensata 219 series hydraulic magnetic circuit protectors combine power switching with reliable circuit protection in a compact, single or multi-pole unit. Utilizing the hydraulic-magnetic principle, these protectors adapt to local applications and environments, minimizing nuisance tripping due to temperature variations. They are ideal for branch circuit applications such as EDP, air conditioners, panel boards, and lighting controls, and are available with various configurations and terminal styles to meet specific needs. The 219 series also withstands high pulses without derating or sacrificing protection, making them suitable for a wide range of industrial applications.
