209/219/229/249/279 Magnetic Circuit Breakers

AIRPAX / Sensata 209/219/229/249/279 Magnetic Circuit Breakers combine power switching with accurate circuit protection in a compact single or multi-pole unit. These E-frame circuit breakers are available in one through six pole assemblies with various configurations and terminal styles. The 209/219/229/249/279 magnetic circuit breakers feature trip-free action. This action prevents the circuit from remaining closed in the presence of an overload, even when the handle is held in the ON position. These circuit breakers include moisture-resistant finishes. The 209/219/229/249/279 circuit breakers are used in EDP, HVAC/R, panel boards, and lighting controls.
