The Sensata APL/UPL series, including the APL111-2REC4-27495-1, are legacy hydraulic magnetic circuit protectors. These devices provide reliable, low-cost power switching, circuit protection, and circuit control. The handle operates like an ON-OFF switch under normal load conditions, but the internal mechanism trips and forcibly opens the contacts upon overload. The protector is 'trip free,' meaning the contacts will not remain closed during an overload, even if the handle is held in the ON position.
This specific model, APL111-2REC4-27495-1, is a 3-pole unit with a lever actuator and panel mount configuration. It is designed for applications requiring precision operation, such as industrial, military, and information processing systems. While this is a legacy product and no new design-ins are accepted, it offers reliable circuit protection.
Sensata Technologies recommends the Airpax™ IAL series as a replacement for new designs. The APL/UPL family is recognized by UL per UL STD. 1077 and certified by CSA per CSA STD. C22.2–No. 235 as supplementary protectors.
