AIRPAX / SENSATA 219320800834 Magnetic Circuit Protector
The AIRPAX/Sensata 209, E-Frame circuit breaker combines power switching with accurate, reliable circuit protection in a compact single or multipole unit. This family of circuit breakers is available in one through six pole assemblies with various configurations and terminal styles to meet diverse application needs. Utilizing the hydraulic-magnetic principle, these protectors adapt to local 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 withstand high pulses without tripping or affecting normal delay curves. The 249 Power Selector Breaker System allows selection of any one of two, three, or four independent power systems, enhancing system flexibility and reliability.
