Eaton Specification Sheet - WER-1/2
Feature → Business Impact → Application: The 32 Vdc, 0.50 A rating ensures targeted protection for low-voltage telecom power feeds, minimizing nuisance trips and extending component life in rack, cabinet, or enclosure installations. This translates to lower maintenance costs and less downtime for critical communication gear in data centers and field networks. Application: Use in telecom power rails to guard against overcurrent events without nuisance tripping in standard 32 Vdc DC distributions. Feature → Business Impact → Application: Non-indicating design reduces visual clutter inside tight enclosures, simplifying service and replacement without upsetting status indicators. Application: Ideal for compact, flat-profile fuse mounting in crowded telecom bays where space is at a premium. Feature → Business Impact → Application: Flat form factor and Bussmann series compatibility enable quick drop-in replacements, lowering installation time and enabling consistent inventory management across sites. Application: Suitable for retrofit projects and new builds requiring standard Bussmann WER devices in 1/2 inch (approx.) footprint. Feature → Business Impact → Application: CE Marked compliance supports regulatory acceptance and minimizes compliance risk for European installations. Application: Great fit for international telecom deployments seeking certified electrical protection components. Feature → Business Impact → Application: 0.50 A current rating aligns with specific circuit protection strategies to prevent damage from surges while preserving service continuity. Application: Use alongside DC-DC converters and telecom line cards to optimize protection margins and reduce warranty claims.
