Frequently Asked Questions
Whose name is on the fuse body?
ernst. 20NH00GL is the Altech Corp. catalog number the stock is held under; the fuse body itself carries the ernst name and the NH 00 C size marking.
Will it fit a North American Class J or Class R fuse holder?
No. Its blades follow DIN 43620, the NH knife-contact standard, so it seats in an NH size 00 fuse base or fuse switch-disconnector.
Is it the same fuse as the 20NH00GL-6?
No. The 20NH00GL-6 is Altech's 690 V version of the 20 A link. This one is rated 500 V AC, printed on the body, so it belongs on systems of 500 V and below.
An NH link is made to go in on a puller, not in bare fingers: the puller clamps the two grip lugs and the blades drive home into the base clips in one straight push. Get the puller on both lugs before you reach for the base.
