AIRPAX / SENSATA 20931664980 Magnetic Circuit Protector
The AIRPAX / SENSATA 209 series hydraulic magnetic circuit protectors offer a compact and reliable solution for branch circuit protection. These breakers combine power switching with accurate protection, making them suitable for applications like EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, the 209 family adapts to local environments, minimizing nuisance tripping due to temperature variations. The design also incorporates an inertial delay for handling inrush currents, a common issue with ferroresonant transformers and capacitive filters. The multi-pole versions feature common-trip construction, ensuring all poles trip simultaneously in case of an overload.
