The Sensata APL3331-5129-1 is a magnetic hydraulic delay circuit breaker featuring a lever actuator and panel mount design. This part belongs to the APL/UPL series, which are legacy products and no new design-in orders are being accepted.
These circuit protectors provide reliable, low-cost power switching, circuit protection, and circuit control. The handle operates like an ON-OFF switch under normal load conditions. Upon overload, an internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The 'trip free' design ensures internal contacts will not remain closed during an overload, even if the handle is held in the ON position.
While designed for industrial, military, and information processing applications, the APL/UPL family is suitable for any situation requiring precision operation. Most versions are recognized by UL and certified by CSA as supplementary protectors.
This specific model, APL3331-5129-1, is noted as obsolete. Sensata Technologies recommends the Airpax™ IAL series as a suitable alternative for new designs.
