The AIRPAX / SENSATA JAE/JRE/JLE series magnetic-hydraulic circuit protector is designed to address circuit protection challenges in high-current applications, particularly those experiencing varying ambient temperatures. Unlike traditional thermal protective devices, the JLE series provides a consistent trip point between -40°C and +85°C. Available in one to six-pole assemblies with diverse configurations and terminal options, this circuit protector is suitable for a wide range of industrial applications, including those requiring compliance with UL-489 and UL-489A standards. Features include an optional mid-trip handle, internal low voltage shunt for current metering, terminal options for design flexibility, multiple trip time delays, and electrical/mechanical auxiliary switches for external monitoring.
