Tenso manufactures the full range of automotive blade fuses — the standard, drop-in auto blade fuse used across vehicle, marine and powersports circuits. The range covers all six common formats, colour-coded to rating, rated for 32 V and 58 V systems, made to ISO 8820 / SAE J1284, with optional blown-fuse indicator versions and fast-acting or time-delay characteristics. Sized to protect the wiring rather than the load, a blade fuse opens before the harness can overheat.
Blade fuse formats — all six
| Format | Quick ID | Typical amps |
|---|---|---|
| Micro2 (APT) | ~9 mm, 2 blades, tall/thin | 5–30 A |
| Micro3 (ATL) | 3 blades (dual-circuit) | 5–15 A |
| Low-Profile Mini (APS) | short body, 2 blades | 2–30 A |
| Mini (APM/ATM) | ~11 mm, 2 blades | 2–30 A |
| Standard (ATO/ATC) | ~19 mm, the classic car fuse | 1–40 A |
| Maxi (APX) | ~29 mm, high-current feeds | 20–100 A |
Voltage: rated 32 V DC for 12 V / 24 V systems, and 58 V for 48 V mild-hybrid systems. Dimensions and ranges are typical — confirm exact ratings against the datasheet.
How to choose
- Amperage — sized to the wire. Pick a rating above the circuit’s normal load but at or below the wiring’s safe current, so the fuse protects the harness.
- Format. Match the format to the holder or fuse box.
- Voltage. 32 V covers 12 V and 24 V circuits; use 58 V for 48 V mild-hybrid systems.
- Response. Standard blade fuses are fast-acting; time-delay versions suit high-inrush circuits.
Don’t fix a blown fuse with a bigger one. A blade fuse protects the wiring. Fitting a fuse larger than the circuit’s wire is rated for removes that protection and is a fire risk — find out why it blew first.
Variants and ratings are indicative; confirm against the datasheet and your circuit’s wire gauge, voltage and ambient before selection.

FAQ
Blade Fuses (ATO / ATC / Mini / Maxi / Micro) — questions buyers ask
What are the types of blade fuse?
Six common formats: Micro2, Micro3, Low-Profile Mini, Mini, Standard (ATO/ATC) and Maxi — differing in size, number of blades and amp range.
What's the difference between ATO and ATC?
Same standard-blade footprint and interchangeable; ATO has an open (exposed) element, ATC a closed (enclosed) one.
What do the blade fuse colours mean?
Each rating has a standard ISO 8820 / SAE J1284 colour — 10 A red, 15 A blue, 20 A yellow, 30 A green, and so on — but always confirm by the number printed on the fuse.
Can I fit a higher-amp blade fuse to stop it blowing?
No. The fuse protects the wiring, so a fuse above the wire's rating is a fire risk. A repeated blow means a fault or an under-rated circuit — diagnose it first.
What voltage are blade fuses?
Most are rated 32 V DC for 12 V / 24 V systems; 58 V versions cover 48 V mild-hybrid systems.
