The AIRPAX / SENSATA JLE-2-1-52-3-B4-250 is a hydraulic magnetic circuit protector within the JAE/JRE/JLE series, engineered to provide robust circuit protection for high-current applications. Unlike traditional thermal protective devices, this protector maintains a consistent trip point across a broad temperature range, from -40°C to +85°C, ensuring reliable performance in challenging environments. Available in one to six-pole assemblies with various configurations and terminal styles, the JLE series offers flexibility for diverse industrial applications. It complies with UL-489 standards and features options like mid-trip handle, internal low voltage shunt for metering, and electrical/mechanical auxiliary switches for external monitoring. Its reduced voltage drop compared to other protective devices enhances efficiency and minimizes energy loss.
