Frequently Asked Questions

What does the aR characteristic mean for this fuse?

The aR (partial range) characteristic means the fuse is designed specifically for semiconductor protection, providing high-speed interruption of short-circuit currents while allowing for low overload currents to pass without nuisance tripping.

Can this fuse be used in DC applications?

No, this particular fuse is rated for AC applications only, as specified in the technical specifications.

How does the striker indication system work?

The striker is a mechanical indicator that activates upon fuse operation, allowing remote signalling devices to detect a blown fuse without direct visual inspection.

Is this fuse RoHS compliant?

Yes, the PC31UD69V400A fuse is RoHS compliant, meeting environmental and safety standards.
