About Tenso
We make the part — we don't just sell it
Tenso is a fuse and circuit-protection manufacturer. Since 2000 we've designed and built fuses, fuse holders, and the switching and disconnection gear that goes around them — in our own plant, with our own tooling, moulding, stamping, assembly, and quality control under one roof.
That's the difference that matters when you source from us: you're dealing with the people who actually make the product, not a trading company reselling someone else's stock. It's why we can hold tight tolerances, take on custom work, and stand behind every part that ships.
What we make
Seven product families cover the full circuit-protection stack:
- Automotive Fuses & Holders — blade fuses (ATO / ATC / Mini / Maxi), fuse boxes, and 12V/24V holders.
- Fuse Holders & Blocks — panel-mount, in-line, DC, and PCB/SMD holders and clips.
- Industrial & HRC Fuses — high-breaking-capacity links and bases, plus fast-acting semiconductor fuses.
- Solar PV Fuses & Holders — 1000V / 1500V DC string protection for installers and EPCs.
- Fuse Switch Disconnectors — isolators and fusible disconnect switches up to 400A.
- Cartridge & Glass Fuses — 5×20 and 6×30 glass and ceramic, fast- and slow-blow.
- Thermal & Temperature Fuses — thermal cutoffs (TCO) and resettable PPTC / polyfuses.
Certified to ship worldwide
Selling protection components into dozens of markets means meeting the standard each one demands. Tenso products are built to comply with CE, UL, RoHS, and REACH — and you can download the certificates here. Every batch is inspected in-house before it leaves the floor, because in circuit protection a part that fails in the field costs far more than one caught on the line.
Custom & OEM manufacturing
Need a fuse or holder built to your own drawing, branding, or specification? Running our own tooling and mould shop means we move from sample to volume production without outsourcing the parts that matter. See Custom & OEM Manufacturing or send us a drawing.
How we work
A component supplier's job is simple to state and hard to do well: build a part that performs exactly as specified, deliver it on time, price it fairly, and stand behind it. We'd rather earn repeat business through reliability than win it once on price — and after more than two decades and 36 countries, that's mostly how we've grown.
