The Sensata APL1111-25978-103 is a hydraulic magnetic circuit breaker from the APL/UPL series, designed for reliable power switching and circuit protection. This unit features a 4-pole configuration with lever actuation, suitable for panel mounting.
As a legacy product, new design-in orders are not accepted for the APL/UPL series. Sensata Technologies recommends the Airpax™ IAL series for new designs. The APL/UPL magnetic circuit protector operates like 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. This 'trip free' design ensures contacts do not remain closed during an overload, even if the handle is held in the ON position.
This circuit breaker is designed for industrial, military, and information processing applications where precision operation is required. Most versions of the APL family are recognized by UL and certified by CSA as supplementary protectors.
