Product Details
Technical Data
 Outline dimensions - EVU10-□ (10~100A body, incl. the 20A model); 72mm overall length, tab terminals Ød with slotted mounting holes |  Time-current characteristics - 10~200A curves (2nd curve from left: 20A); virtual pre-arcing time vs prospective current for fuse coordination |
 EVE10 family dimensions - single / AX2 dual-parallel / AX4 quad-parallel bodies (100~800A) for scaling the same platform to battery and DC feeder protection |  Time-current characteristics - 70~600A curves for upstream/downstream coordination with the 20A model in your protection cascade |
Why Choose the EVU10-20A?
| Advantage | Benefit for Your Application |
|---|---|
| ✅ 20kA DC Breaking @ 1000VDC | Interrupts up to 20,000A fault current at 1000VDC (L/R = 10ms) - reliable protection for high-voltage EV, PDU and energy-storage DC circuits. |
| ✅ Low I2t - Protects Semiconductors | Pre-arcing I2t of only 61 A2s and 275 A2s total clearing - limits let-through energy so IGBTs, SiC modules and wiring stay within their thermal limits. |
| ✅ gR Full-Range Class | One fuse covers both overload and short-circuit zones - no need to coordinate separate aR (short-circuit-only) and gG fuses, simplifying your protection design. |
| ✅ Only 1.7W Power Loss | Low watts loss at 100% rated current keeps heat down inside sealed PDU boxes and battery compartments - no derating headaches in compact layouts. |
| ✅ Flexible End-Tab Termination | Flexible tabs with slotted holes bolt directly to busbars or lugs - fast installation and easy replacement in service. |
| ✅ One Platform, 10A~800A | The same EVU10/EVE10 platform scales from 10A branch circuits to 800A main feeders (up to 50kA breaking) - one protection family for the whole DC chain. |

Frequently Asked Questions
Q1. Where is the EVU10-20A typically used?
A: As branch-circuit protection in EV power distribution units (PDU), DC/DC converters, IGBT/SiC inverter DC links, energy-storage battery sub-circuits and motor drive systems - any DC circuit up to 1000VDC carrying around 20A.
Q2. What does gR full-range class mean?
A: A gR fuse protects against both overloads and short circuits across the whole characteristic - unlike aR (short-circuit-only) fuses. That single-device coverage makes gR ideal for protecting cables and power semiconductors at the same time.
Q3. Why is the low I2t important?
A: I2t is the let-through thermal energy during clearing. With only 61 A2s (pre-arc) / 275 A2s (total), the fault is cut off before IGBT/SiC modules or wiring exceed their thermal limits - the key coordination parameter for semiconductor protection.
Q4. How do I coordinate it with larger fuses upstream?
A: Use the time-current curves in Technical Data: the 20A curve must sit below (faster than) the upstream fuse curve over your fault-current range. Charts for 70~600A models are included for cascade design.
Q5. What is the family range?
A: The EVU10/EVE10 platform covers 10A~800A: EVU10-10~100 (20kA breaking), -B/-C/-D series 100~600A (50kA), EVE10 -A/-AX2/-AX4/-AP parallel-body versions up to 800A. Contact us for the full datasheet.
Q6. How is it mounted?
A: The fuse body carries flexible end tabs with slotted holes - bolt directly onto busbars or cable lugs. Overall outline and terminal dimensions are shown in the EVU10-□ (10~100A) drawing in Technical Data.
