The Sensata APL1-1-52-703-M is a single-pole hydraulic magnetic circuit breaker designed for reliable power switching, circuit protection, and control. It offers a current rating of 70A and a voltage rating of 277V.
This circuit breaker features a lever actuator for manual operation, similar to an ON-OFF switch. In the event of an overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The protector is designed to be 'trip free,' meaning the internal contacts will not remain closed under overload conditions, even if the handle is held in the ON position.
Designed for panel mounting, the APL1-1-52-703-M is suitable for various industrial, military, and information processing applications where precision operation is required. It is part of the APL/UPL series, which offers multiple configurations including series, shunt, and relay types with various delays and ratings. This specific model is a legacy product and no new design-in orders are being accepted.
Sensata Technologies recommends utilizing the Airpax™ IAL series as an alternative for new designs. 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.
