APL01-1223-1

The Sensata APL/UPL series APL01-1223-1 is a hydraulic magnetic circuit breaker designed for reliable power switching and circuit protection. This model features a lever actuator for manual operation and is designed for panel mounting.

This circuit breaker provides reliable, low-cost power switching, circuit protection, and circuit control. The handle opens and closes a circuit under normal load conditions, similar to an ON-OFF switch. Upon overload, the internal mechanism trips, opens the contacts, and forcibly returns the handle to the OFF position. The protector is "trip free," meaning the internal contacts will not remain closed in the presence of an overload, even if the handle is held in the ON position.

The APL/UPL line offers many 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 is suitable for use in any situation where precision operation is required. This specific part is designated with the UPL prefix, indicating it is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235 as a supplementary protector.

Important Notice: The APL/UPL is a legacy product and no new design-in orders are being accepted. Sensata Technologies recommends utilizing the Airpax™ IAL series for new designs.
