Product details

The DF3FN100 is a TeSys GS NFC cartridge fuse — 22 x 58 mm body, gG (general-purpose) curve, rated 100 A at 500 V AC. The striker pin pops out on the blown fuse, giving local visual indication at the disconnector.

The 22 x 58 mm physical size is standard across many European-style fuse disconnectors; if your existing holder accepts that body length and diameter, the DF3FN100 slots in without adapter hardware. The gG curve is the workhorse for general cable and equipment protection, not for semiconductor or motor-start duty (those want aR or gM curves respectively).

Frequently asked questions

What is the closest alternative to DF3FN100 in the TeSys GS family?

The DF3FN100 is a specific variant — 100 A, gG curve, with striker. Within the same TeSys GS range, other order codes differ by current rating (e.g., 63 A, 125 A) or by fuse curve (aM for motor protection). There is no direct pin-compatible replacement with identical ratings; the correct alternative depends on the load and coordination study. For a like-for-like swap at 100 A gG with striker, you are looking at surplus stock of this exact code.

How do I source DF3FN100 given its obsolete status?

Since it is obsolete, standard distributor stock is depleted. Sourcing is through surplus, liquidation, or broker channels — quoted to order against an RFQ. Expect to buy the full set of 10 as a single lot.
