Why Choose the EVU8.0-200-B?
| Advantage | Benefit for Your Application |
|---|---|
| ✅ 60kA @ 800VDC Breaking | Clears the highest fault currents in 800V-class EV charging, ESS and DC distribution systems - rated with L/R=10ms time constant typical of battery circuits. |
| ✅ Fast-Acting gEV Protection | Current-limiting action with only 5,237 A2s pre-arcing I2t - reacts faster than IGBT/SiC short-circuit withstand, protecting expensive semiconductor devices in PDU, DC-DC and motor drives. |
| ✅ Low 27W Power Loss | Efficient at 100% load - less heat in sealed charging-pile cabinets and battery boxes, lower cooling burden and stable continuous 200A operation. |
| ✅ One Footprint 100-400A | All B-type ratings share the identical 97 × 75mm, Ø31mm body - upgrade protection rating later without redrawing the busbar or mount. |
| ✅ Full 10-600A Family | From 10A aux circuits to 600A main loops (30/50/60kA classes) in one brand - simplify sourcing for chargers, PDUs and storage racks. |
| ✅ Certified, 3-Year Warranty | IEC standard compliance with CE marking; backed by a 3-year warranty - dependable for EV charger and ESS OEM projects. |

Frequently Asked Questions
Q1. What is the EVU8.0-200-B used for?
A: It is a 200A / 800VDC fast-acting fuse for EV chargers, energy storage systems, PDUs (DC-DC conversion), IGBT and other semiconductor devices, electric vehicles, compressors and motor drives - anywhere a high-voltage DC branch or main circuit needs short-circuit protection.
Q2. Why does "fast-acting" matter for semiconductors?
A: IGBT and SiC devices tolerate fault current for only microseconds to milliseconds. The gEV fast-acting element limits let-through energy to just 5,237 A2s (pre-arcing), clearing the fault before the semiconductor's short-circuit withstand is exceeded.
Q3. What does 60kA @ 800VDC (L/R=10ms) mean?
A: The fuse can safely interrupt a prospective short-circuit current of 60,000A at 800VDC in a circuit with a 10ms time constant - the inductive profile typical of battery-backed DC systems in EV and storage applications.
Q4. How do I select between B-type ratings?
A: Pick the rating to match continuous load current (with derating for ambient temperature and enclosure), then verify the I2t coordination: the fuse's total clearing I2t (21,470 A2s for 200A) must stay below the protected device's withstand. All B ratings share the same 97 × 75mm footprint, so upsizing needs no remounting.
Q5. What are the mounting dimensions?
A: B-type (100-400A): 97mm overall length, 75mm terminal span, Ø31mm ceramic body, 8×13mm knife terminals with mounting holes - see the dimension drawing above; C and D types (350-600A) use larger Ø38/Ø51 bodies.
Q6. What certification and warranty are provided?
A: Manufactured to IEC standards with CE marking (label also references the ISO 8820 / IEC 60269 family), and covered by a 3-year warranty. Certificate copies are available on request.
