❓ Frequently Asked Questions

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

A: Curve D on the 3WX3663-6JELD trips magnetically at 10–20× rated current, making it ideal for highly inductive loads with large inrush — transformers, large motors, welding machines. 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.
