Descripción

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.
