Why Tenso
You're buying from the factory — not a middleman
Tenso has designed and built fuses and circuit-protection gear since 2000 — in our own plant, with our own tooling, moulding, stamping, assembly and quality control under one roof. That's why buyers in 36+ countries source direct: tighter control, faster answers, and a supplier that stands behind every part that ships.
Why source from Tenso
Six reasons buyers choose manufacturer-direct
No trading-company markup and no telephone game with a sub-supplier — design, tooling, production and QC all sit under one roof.
We make the part
Tooling, moulding, stamping, assembly and QC under one roof — you deal with the people who actually make the product, not a trading company reselling someone else's stock.
Inspected, every batch
100% in-house batch inspection before anything ships. In circuit protection, a part that fails in the field costs far more than one caught on the line.
Custom & OEM without friction
Running our own mould shop, we move from sample to volume without outsourcing the parts that matter — to your drawing, rating, packaging or brand.
Certified to ship worldwide
Built to comply with CE, UL, RoHS and REACH, with certificates and declarations available on request — so your QA team gets what it needs.
One supplier, full stack
Seven product families from blade fuses to HRC links, PV string protection, disconnect switches and thermal cutoffs — one set of documents, one point of contact.
Engineering when you need it
Send a part number, a reference brand, or a circuit description — our team confirms fit, ratings and approvals instead of forwarding your email to a third party.
Under one roof
What manufacturer-direct actually means
When you source from Tenso, your RFQ goes to the team that runs the moulds, stamps the contacts, assembles the holders and signs off the batch test report — not to a sales desk that forwards it to an anonymous factory.
That changes what you can ask for: tighter tolerances on a custom blade fuse, a holder built to your panel cut-out, a private-label box for your distribution channel, or a cross-reference to a Littelfuse, Bussmann or Mersen part you're replacing. We can hold the conversation because we control the process.
- Tooling, moulding, stamping and assembly in-house
- Batch inspection and continuity checks before shipping
- Sample-to-volume path without outsourcing critical steps
- Documents and certificates from the source, not a broker

Manufacturer vs middleman
What changes when you cut out the broker
Trading companies can move boxes. A manufacturer can change the box, the part inside it, and the test report that goes with it.
Certified
Compliance you can hand to your QA team
Selling protection components into dozens of markets means meeting the standard each one demands — with paperwork to match.
Conformity for the European market across applicable product lines.
UL recognition or listing on qualifying fuse and holder ranges.
Restricted-substance compliance for electronics supply chains.
REACH compliance for chemical-substance reporting in the EU.
Custom & OEM
From first sample to volume — without losing control
Need a fuse or holder built to your drawing, branding or specification? Running our own tooling and mould shop means we move from sample to production without outsourcing the parts that matter.
- Custom ratings, housings, colours and packaging
- Private-label and your part number on the label
- Tooling owned and maintained in our plant
- Engineering review before tooling is cut
Samples, MOQ & lead time
Built for real production schedules
Standard blade fuses, holders and common industrial ratings stay in production rotation — so repeat orders don't restart the clock. For new parts, we quote sample lead time, MOQ and volume pricing together so you can plan your build.
- Quote confirmation within one business day
- Samples available for evaluation and agency testing
- MOQs sized to the part — ask, don't assume catalogue minimums
- Repeat-order lead times from active production lines
