The Airpax UPGB9660-1REG4-27471-2 is a single-pole hydraulic-magnetic circuit protector engineered for precision protection in applications demanding temperature-stable trip characteristics. Unlike thermal devices, its hydraulic-magnetic operating principle delivers consistent trip current independent of ambient temperature variations, making it ideal for military, marine, broadcast, and data processing environments where nuisance tripping cannot be tolerated.
