AIRPAX / SENSATA 21920SW7977 Magnetic Circuit Protector
The AIRPAX/SENSATA 209, 219, 229, 249, and 279 series hydraulic magnetic circuit protectors offer a robust solution for branch circuit protection. These circuit breakers combine power switching with accurate and reliable protection in a compact, single or multi-pole unit, suitable for applications like EDP, air conditioners, panel boards, and lighting controls. Utilizing the hydraulic-magnetic principle, these protectors adapt to various environments and minimize nuisance tripping due to temperature variations. They are designed to withstand high pulses without affecting normal delay curves, making them ideal for applications with inrush currents from ferroresonant transformers, lamps, and capacitive filters.
