Piaggio 290402 Complete Fuse Holder with 7.5 A Fuse – Vespa PX, Zip, Typhoon and Ape

The complete Piaggio 290402 fuse holder is the small black box with a transparent lid that protects the electrical system downstream of the battery on most Piaggio Group scooters from the 90s and 2000s — from the Vespa PX to the Zip, from the Typhoon to the Ape Poker. It comes already complete with a 7.5 A blade fuse. Official catalog designation: "Fuse holder compl.". Product code 290402.

✓ Strengths

• Complete with fuse – the package already contains the brown 7.5 A blade fuse: no need to buy it separately.
• Transparent cover – you can see if the fuse is blown without disassembling anything, and it protects the contacts from water and dirt.
• Original spare part – it is the code prescribed by the manufacturer in the catalog, with the correct connections and attachment for the standard location.
• One code for dozens of models – the same fuse holder fits Vespa, Piaggio, Gilera, and Ape, from 50 to 200 cc.
• Part that ages poorly – on these vehicles, the original fuse holder is often cracked, oxidized, or has loose tabs: it's a classic cause of intermittent electrical failures.

Technical features

Vehicle compatibility

List taken from the official Piaggio spare parts catalog (B2B). The assignments are very numerous: here they are grouped by brand and family. If your model is not listed, send us the frame number and we will verify it.

To check together

• 290405 – the fuse holder support, i.e., the bracket that holds it to the frame: it often breaks and is a separate code.
• Battery cables and terminals – if the fuse holder was oxidized, the terminals leading to it almost certainly are too.

Who it's perfect for

This is the part needed by anyone putting an twenty-year-old Piaggio or Gilera scooter or a Vespa PX back on the road and finding the fuse holder cracked, with the cover lost, or the contacts green with oxidation. It costs little, can be replaced in five minutes, and eliminates one of the most frequent causes of intermittent electrical failures — those where the bike starts one day and not the next. It also serves as a spare part to keep under the seat.

Frequently asked questions

Is the fuse included?
Yes: the 290402 is the complete fuse holder and comes with its 7.5 A blade fuse already inserted, the brown one you see in the second photo. You don't need to buy anything separately, except for the 290405 support if yours is broken.

Is it suitable for my Vespa PX?
Yes: the Piaggio catalog indicates it for the Vespa PX 125 E, PX 150 E and PX 200 E from historical catalogs, for the PX 125 30 Anni from 2007-2008 and for the PX 125 and 150 2T E3 from 2011 to 2017. It is the same part mounted on ET2, ET4, Zip, Typhoon and Ape Poker.

Can I install a 10 or 15 A fuse?
No. The specified amperage for this system is 7.5 A and must be respected: a larger fuse does not "solve" anything, it simply stops protecting the system and allows the wires or devices to burn out, with much more costly damage.

How do I know if the fuse holder needs replacing?
Signs include a cracked or missing cover, blackened or green with oxidation contacts, tabs that no longer hold the fuse, and especially electrical failures that come and go when moving the cables. If the fuse rattles in its seat, this is the replacement you need.
