GFEVT1000‑38R ev dc fuse is aR‑class high‑speed bolt‑mount DC fuse dedicated for energy‑storage systems and EV battery‑pack protection. Rated 250A‑400A at 1000V DC with 50kA high breaking capacity and time‑constant ≤5 ms. It uses M8 mounting bolt with recommended installation torque 12±1.0 N.m. The fuse supports parallel installation for higher ampacity within dimensional guidelines. It delivers superior anti‑shock & anti‑vibration performance ≥20g acceleration. For high‑altitude applications between 2000‑4500 m, derating for rated‑current and insulation distance correction shall be considered. Manufactured to IEC60269.4, UL248‑13, JASO‑D622 standards, CE marked, RoHS‑compliant, REACH declaration available upon request.

Frequently Asked Questions

Q: What fuse class is GFEVT1000‑38R ev dc fuse?
A: GFEVT1000‑38R belongs to aR high‑speed DC fuse, specially designed for energy‑storage and EV battery‑pack short‑circuit & over‑current protection.
Q: What is breaking‑capacity and time‑constant of GFEVT1000‑38R?
A: Rated interrupting capacity is 50kA at 1000V DC; time‑constant ≤5 ms for fast fault clearing for high‑power DC systems.
Q: What mounting requirement for GFEVT1000‑38R?
A: M8 bolt‑on installation; recommended tightening torque 12±1.0 N.m to guarantee stable electrical contact.
Q: Does GFEVT1000‑38R work at high altitude above 2000 m?
A: For altitude 2000‑4500 m, rated‑current derating and insulation‑gap correction are required, especially for closed‑box installation scenarios.
Q: Can multiple GFEVT1000‑38R fuses run in parallel?
A: Yes, parallel mounting is allowed within dimensional guidelines to achieve higher total ampacity for large‑scale energy‑storage projects.
