The Sensata APL1-1-61-203 is a single-pole circuit breaker from the APL/UPL series, featuring a magnetic hydraulic delay mechanism for reliable protection. It has a current rating of 20A and a voltage rating of 277V AC.
This circuit breaker is designed for panel mounting and utilizes a lever actuator for manual operation. The magnetic hydraulic design ensures that the circuit is forcibly opened upon overload, even if the handle is held in the ON position, providing trip-free operation.
While the datasheet indicates this is a legacy product and not recommended for new design-ins, it offers established performance for existing applications. Sensata Technologies recommends the Airpax™ IAL series for new designs. The APL/UPL family is recognized by UL and certified by CSA as supplementary protectors.
Key specifications include a 20A current rating, 277V voltage rating, and a lever actuator. It is suitable for applications requiring precise operation and reliable circuit control.
