The Sensata UPL1-21430-4 is a single-pole circuit breaker from the APL/UPL series, utilizing a magnetic-hydraulic delay mechanism for reliable protection. It features a lever actuator 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 cannot be held closed during an overload condition, even if the handle is manually held in the ON position.
Designed for industrial, military, and information processing applications, this circuit breaker offers dependable power switching, circuit protection, and control. Its panel mount design facilitates integration into various systems. The APL/UPL series is recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235.
This legacy product is noted as 'Existing Design-In Only' by the manufacturer, with no new design-in orders being accepted. Sensata Technologies recommends the Airpax™ IAL series as a suitable alternative for new designs.
