Description

H10F fast dc automotive fuse is gR full‑range fast‑acting fuse for comprehensive circuit protection of instrument power lines and vehicle wiring harnesses. Current range covers 0.44A‑50A, rated DC voltage 150‑1000V (450‑500V for 10‑50A), AC 250‑500V. Interrupting capacity: 20kA DC, 50kA AC. Adopt 99.99% pure‑silver melt, high‑purity quartz‑sand arc‑extinguishing medium; melamine tube for 0.44A‑30A, ceramic tube for 35A‑50A. Contact surfaces are silver‑plated to lower temperature rise and power consumption. Melt terminals are spot‑welded for reliable short‑circuit fault breaking. Operating ambient temperature‑40 ℃ ~ +125 ℃. It resists thermal shock, mechanical shock, current impulse and chemical load. Custom‑made agreed time‑current performance can be negotiated for special‑project requirements.
