APL111-1REC4-2920-19

The Sensata APL111-1REC4-2920-19 is a hydraulic magnetic circuit breaker from the APL/UPL series. This unit features a 3-pole configuration, designed for reliable power switching, circuit protection, and control. It is equipped with a lever actuator for manual operation and a panel mount for secure installation.

This circuit protector 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 be held closed during an overload, even if the handle is manually held in the ON position.

While designed for industrial, military, and information processing applications, the APL/UPL series is suitable for any situation requiring precision operation. It is important to note that the APL/UPL series is a legacy product, and Sensata Technologies recommends the Airpax™ IAL series for new design-ins. Most versions are recognized by UL and certified by CSA as supplementary protectors.

Key specifications include a panel mount type and a lever actuator. The breaker is a 3-pole unit, offering robust protection for multiple circuits. The APL/UPL line supports various configurations, including series, shunt, and relay types, with a choice of delays and ratings, and multi-pole assemblies can accommodate a mix of these options.
