The Sensata APL/UPL series hydraulic magnetic circuit protector, part number APL2-9739-27, offers reliable power switching, circuit protection, and control. It features a lever actuator for manual operation, functioning 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. This protector is 'trip free,' meaning the contacts will not remain closed during an overload, even if the handle is held in the ON position.
Designed for industrial, military, and information processing applications, this circuit breaker is suitable for any situation requiring precision operation. It is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. The APL/UPL line offers various configurations, including series, shunt, and relay types, with a choice of delays and ratings. Multi-pole assemblies are also available.
This specific model, APL2-9739-27, is designated with the UPL prefix and is designed for panel mounting. 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.
