UPL1-25987-1

The Sensata UPL1-25987-1 is a magnetic hydraulic delay circuit breaker featuring a single pole and a lever actuator for manual operation. It is designed for panel mounting, offering reliable circuit protection and power switching. This product is part of the APL/UPL series, which is noted as a legacy product with no new design-in orders being accepted. Sensata Technologies recommends the Airpax™ IAL series as a suitable alternative for new designs.

The APL/UPL series circuit protectors are designed for industrial, military, and information processing applications where precision operation is required. They function similarly to an ON-OFF switch but automatically trip and open the circuit upon detecting an overload. The 'trip-free' mechanism ensures the internal contacts cannot be held closed during an overload condition, even if the handle is manually held in the ON position.

This specific model, UPL1-25987-1, is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. While specific current and voltage ratings are not detailed here, the series offers various configurations including series, shunt, and relay types with a choice of delays and ratings.
