❓ Frequently Asked Questions

Q: Why is Curve C specified for the 3WX3663-6JELC and what loads is it optimised for?

A: Curve C on the 3WX3663-6JELC trips magnetically at 5–10× rated current, making it ideal for general-purpose circuits including fluorescent lamps, small motors, and mixed loads. Using the wrong curve can cause nuisance tripping (too sensitive) or inadequate protection (not sensitive enough). Always match the curve to the load’s inrush characteristics.
