## Description
The Bel Fuse 0ALEB9100-PD is a 500V DC-rated automotive fuse from the 0ALE Series, engineered specifically for high-voltage accessory circuit protection in Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), and Energy Storage Systems (ESS). This 10A stud-mount fuse with offset blade terminals features a ceramic body construction with tin-plated copper caps and terminals, delivering robust thermal and mechanical integrity for demanding automotive environments. The fuse complies with ISO 8820-8, GB/T 31465.6, and UL 248-20 EV fuse standards, with an interrupting rating of 20kA DC at rated voltage. Electrical characteristics include 13.5 mΩ typical cold resistance, 185 mV typical voltage drop, and 130 A²sec typical pre-arcing I²t measured at 10× rated current. Operating temperature spans -40°C to +125°C with appropriate derating factors applied.
Designed for individual component and internal circuit protection within EV/HEV/ESS architectures, the 0ALEB9100-PD addresses the critical need for reliable DC fault current interruption in 500V nominal battery systems and auxiliary power distribution networks. The stud-mount configuration with M5 screw terminal accepts recommended tightening torque of 3.5–4 Nm, facilitating secure mechanical attachment and low-impedance electrical connection in high-vibration automotive applications. The 64.3mm × 10mm × 13.2mm form factor accommodates space-constrained installations while maintaining adequate creepage and clearance distances for 500V operation. RoHS compliance per EU Directive 2011/65/EU and amending directive 2015/863 ensures environmental regulatory adherence for global automotive supply chains.
Packaged in plastic tray format (40 pieces per tray, 400 pieces per carton), the 0ALEB9100-PD supports high-volume manufacturing requirements. The fuse marking includes Bel logo, series designation 0ALE, current rating, and voltage rating for clear circuit identification, with additional label documentation specifying interrupting rating and China RoHS compliance status. This component serves as primary protection for DC-DC converters, battery management system auxiliary circuits, HVAC systems, and other high-voltage accessories where coordinated protection with upstream battery disconnect units is essential for safe system operation.
