Eaton British Standard Fuse A3 100A 500V AC High Rupture Capacity Offset Tag 73.5 mm OSD100

Eaton OSD100 is a British Standard Fuse, model OSD100, rated at 100A current and 500V AC voltage, designed to protect electrical equipment from overcurrent and short circuit faults in industrial and commercial environments.

This fuse serves as a weak link that melts under fault conditions to break the circuit safely, offering a high rupture capacity that prevents explosion or electrical arcing during interruption.

The offset tag design with fixing centres of 73.5 mm and tag width of 12.7 mm allows secure installation in fuse holders. It has an overall length of 95 mm, length of 54.5 mm, height of 54.5 mm and diameter and width of 21 mm each, making it suitable for standard electrical setups.

Manufactured under strict RoHS conformity, the fuse has low temperature rise, enabling high-density mounting within control panels and switchgear.

Typical use cases include industrial switchgear protection, heavy machinery, electrical distribution networks, and three-phase power systems requiring type 2 coordination as per IEC 947-4 standards.

100A current rating for robust electrical protection. High rupture capacity (HRC) construction. Offset tag for bolted mounting in fuse holders. Conforms to British Standard Fuse size A3. 500V AC rated for safe alternating current operation.

Complies with RoHS environmental standards. Dimensions optimized for standard electrical equipment installation. Designed for reliable and safe interruption of electrical faults.

This Eaton fuse is ideal for electricians and engineers requiring dependable overcurrent protection compliant with British and international standards. It is suitable for replacement applications in existing electrical infrastructure or new system installations.
