The Sensata APL/UPL series APL1-1669-3 is a single-pole hydraulic magnetic circuit breaker featuring a lever actuator for manual operation. It is designed for panel mounting, offering reliable circuit protection and power switching.
This circuit breaker operates similarly to an ON-OFF switch under normal load conditions. Upon detecting an overload, its internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The 'trip-free' design ensures the internal contacts cannot remain closed during an overload, even if the handle is held in the ON position.
It is important to note that the APL/UPL series, including this part, is a legacy product. Sensata Technologies is no longer accepting new design-in orders for this series and 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.
Most versions of the APL family are recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235 as supplementary protectors.
