The Sensata APL/UPL series, including the APL1-1669-15, are hydraulic magnetic circuit protectors designed for reliable power switching, circuit protection, and control. This specific model features a single pole, a lever actuator for manual operation, and a panel mount for easy integration into systems.
These protectors function like an ON-OFF switch under normal load conditions. Upon detecting an overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The "trip free" design ensures the internal contacts cannot be held closed during an overload, even if the handle is manually held in the ON position.
While designed for industrial, military, and information processing applications, the APL/UPL series is suitable for any situation requiring precision operation. It is important to note that the APL/UPL series is a legacy product, and no new design-in orders are being accepted. Sensata Technologies recommends the Airpax™ IAL series as a suitable alternative for new designs.
This product is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. The UPL prefix designates versions certified by CSA.
