Airpax APL111-1378-70 Three Pole Circuit Breaker

Airpax APL111-1378-70 Three Pole Circuit Breaker is a three-pole magnetic circuit protector from the Airpax APL/UPL series, housed in a molded phenolic case for durable panel installations. It carries a 7.5 A current rating and uses a magnetic trip mechanism to interrupt current quickly on overloads, protecting connected equipment. The three poles are designed to operate in unison through a linked-trip construction, and the unit is UL and CSA recognized as a supplementary protector when installed in compatible configurations. This model fits industrial power-distribution and motor-protection roles, safeguarding three-phase motors, transformers, and distribution panels in manufacturing, energy, and data-center environments that require reliable three-phase protection. For procurement, APL111-1378-70 represents a specific assembly within the APL111 family, aligning with legacy Airpax installations and the current Sensata Airpax catalog when verifying compatibility with voltage ratings and mounting footprints.
