UPL0-1REC4-28341-1

The Sensata UPL0-1REC4-28341-1 is a magnetic hydraulic delay circuit breaker from the APL/UPL series. It is designed for reliable, low-cost power switching, circuit protection, and circuit control. The breaker features a lever actuator for manual operation, similar to an ON-OFF switch. Upon overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. This protector is 'trip free,' meaning the internal contacts will not remain closed under overload conditions, even if the handle is held in the ON position.

This specific model is designed for panel mounting. The APL/UPL series offers various configurations, including series, shunt, and relay types, with a choice of delays and ratings. Multi-pole assemblies are also available. While designed for industrial, military, and information processing applications, the APL/UPL series is suitable for any situation requiring precision operation.

IMPORTANT NOTICE: The APL/UPL series is a legacy product. No new design-in orders are being accepted, and the 205 series is being discontinued. Sensata Technologies recommends utilizing the Airpax™ IAL series 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.
