This Sensata APL1111-1-42-503-AB is a hydraulic magnetic circuit protector designed for reliable power switching and circuit control. It features a 50A current rating and a 277V voltage rating, with four poles for multi-circuit protection.
The breaker type is magnetic with a hydraulic delay, offering precise overload protection. The actuator type is a lever, allowing for manual operation similar to an ON-OFF switch. Upon detecting an overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. This 'trip free' design ensures the contacts will not remain closed under fault conditions, even if the handle is held in the ON position.
Designed for industrial, military, and information processing applications, this circuit breaker is suitable for systems requiring precise operation. It is recognized by UL and certified by CSA as a supplementary protector.
The unit is designed for panel mounting. While the datasheet indicates this is a legacy product and no new design-in orders are accepted, existing systems may still utilize it.
