JLE Hydraulic Magnetic Circuit Breakers

Sensata / AIRPAX JLE Hydraulic Magnetic Circuit Breakers are UL 489 Listed, F‑frame circuit breakers designed to provide reliable overcurrent protection in high-current applications. The Sensata / AIRPAX JLE is the principal member of the JAE / JRE / JLE family and delivers stable, repeatable trip performance across a wide operating temperature range of -40°C to +85°C. JLE circuit breakers use hydraulic magnetic technology to maintain consistent protection characteristics regardless of ambient temperature, making the series well-suited for demanding environments where thermal breakers may be less predictable. Advanced internal construction supports high interrupting capacity while minimizing voltage drop through the breaker. JLE breakers are available in single‑ and multi‑pole configurations, with a variety of actuator styles, trip delays, and termination options to support flexible panel-mount system designs.
