In today’s applications, ambient operating temperatures present circuit protection challenges for many design engineers. High current thermal protective devices may not provide the desired degree of protection.
The JAE/JRE/JLE 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 JAE/JRE/JLE series is actually a family of circuit protectors available in one to six pole assemblies with a variety of configurations and terminal styles.
The principle member of this family is the JLE, an F-frame “listed circuit breaker” which complies with conditions of UL-489.

Other members of the family include the JTE, for telecommunication applications and complies to UL-489A, and the JAE, a special construction version.
In addition, the JAE is now in compliance with the standards used in Australia and New Zealand, AS 60947.2-2005 (equivalent to IEC 60947-2:2006+A1).

The JAE/JRE/JLE series magnetic-hydraulic circuit protector provides circuit protection for high current applications.
It provides a consistent trip point over temperatures ranging from –40°C to +85°C.

Features

• Mid-trip handle available for visual identification of fault-tripped circuit breakers
• Optional internal low voltage shunt to meter current (single and multi-pole units are dimensionally equivalent in depth)
• Terminal options for design flexibility in various applications
• Multiple trip time delays for application flexibility
• Electrical and mechanical actuated auxiliary switch options for external monitoring of circuits
• Reduced voltage drop through the circuit breaker vs. other circuit protective devices
