The JLE/JRE Series magnetic hydraulic circuit protector addresses this issue by providing circuit protection for high current applications with a consistent trip point over temperatures ranging from –40°C to +85°C. The JLE/JRE Series is actually a family of circuit protectors available in one to six-pole assemblies with a variety of configurations and terminal styles. The principal member of this family is the JLE, an F-frame “listed circuit breaker” which complies with conditions of UL-489.
