Frequently Asked Questions

What does the aR speed characteristic mean?

The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by interrupting short-circuit currents quickly while allowing harmless overloads to pass without blowing.

Is this fuse suitable for DC applications?

No, this particular fuse is rated for AC applications only, as indicated by the AC or DC specification.

Can this fuse be used in existing British Standard fuse holders?

Yes, the 17x49mm size and mounting style make it compatible with standard British Standard holders designed for this fuse size.

What is the breaking capacity of this fuse?

The fuse has a maximum breaking capacity of 200 kA at rated voltage, suitable for high fault current interruption.
