FAQs

What is the purpose of the JD-5E Integrated Motor Protector?

It safeguards three-phase AC motors from overload and phase failure, preventing motor damage during voltage imbalance or excessive load conditions.

What is the rated current and voltage range?

The JD-5E operates up to 400 A and 690 V, suitable for motors from 0.5 kW to 200 kW.

How is the current adjusted?

A rotary knob allows for continuous adjustment of the setting current within the model’s rated range.

What are its tripping characteristics?

For currents up to 80 A, the tripping level is Class 10A. For 80–400 A models, users can select Class 10A, 10, 20, or 30, depending on the application.

How does the JD-5E indicate operational status?

Three LED indicators display phase-failure, running, and overload conditions for quick visual diagnostics.
