The Sensata APL/UPL Series APL111-1REC4-41-102-AM is a hydraulic magnetic circuit protector designed for reliable power switching, circuit protection, and control. This 3-pole breaker offers a current rating of 1A and a voltage rating of 277V.
It functions similarly to an ON-OFF switch under normal load conditions, but its internal mechanism trips and forcibly opens the contacts upon overload. The protector is 'trip free,' meaning the internal 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 features a lever actuator for manual control and a panel mount for secure installation. The APL/UPL line offers various configurations, including different delays and ratings, and multi-pole assemblies can combine these features.
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. It is important to note that the APL/UPL series is a legacy product, and new design-in orders are not being accepted. Sensata Technologies recommends utilizing the Airpax™ IAL series for new designs.
