APL211-9739-20

The Sensata APL/UPL series hydraulic magnetic circuit protector, specifically the APL211-9739-20 model, offers reliable power switching and circuit protection. It features a panel mount design with a lever actuator for manual operation, functioning similarly to 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. This protector is 'trip free,' ensuring it cannot be held closed during an overload.

This APL/UPL series is a legacy product and is not accepting new design-in orders. Sensata Technologies recommends the Airpax™ IAL series for new designs. While designed for industrial, military, and information processing applications, its precision operation makes it suitable for various systems requiring reliable circuit control. The APL/UPL line offers multiple configurations, including series, shunt, and relay types, with various delays and ratings available. Multi-pole assemblies are also possible, combining different current ratings, delays, and internal circuit configurations.

Key specifications include its magnetic (hydraulic delay) breaker type and panel mount capability. The product is designated with the UPL prefix, indicating recognition by UL and certification by CSA as supplementary protectors. While RoHS, MSL, and REACH statuses are listed, they are marked as unverified in the database and should be treated with low confidence.
