The Sensata APL111-1-42-752 is a hydraulic magnetic circuit breaker from the APL/UPL series, designed for reliable power switching and circuit protection. This 3-pole unit offers a current rating of 7.5A and a voltage rating of 277V.
Featuring a panel mount design and a lever actuator, this circuit breaker provides clear ON/OFF indication. The magnetic-hydraulic delay mechanism ensures protection against overloads by tripping the internal contacts and forcibly returning the handle to the OFF position. The protector is trip-free, meaning it cannot be held closed during an overload condition.
This legacy product is suitable for applications requiring precision operation, including industrial, military, and information processing systems. While no new design-in orders are accepted, existing systems may utilize its specifications. Sensata Technologies recommends the Airpax™ IAL series for new designs.
Key specifications include a 7.5A current rating, 277V voltage rating, and a 3-pole configuration. The breaker type is magnetic (hydraulic delay), and it is designed for panel mounting.
