The AIRPAX / SENSATA 219-3-1-60-5-9-100 is a hydraulic magnetic circuit protector within the 209 series family. This circuit breaker combines power switching with accurate and reliable circuit protection in a compact, single or multi-pole unit. It's ideal for branch circuit applications such as EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, the 209 family adapts to local applications and environments, minimizing nuisance tripping due to temperature variations. The inertial delay feature is standard for 50/60Hz units, offering protection against inrush currents from transformers, lamps, and capacitive filters. The protector withstands high pulses without tripping, ensuring consistent performance and protection.
