Why Choose the Mersen BTIS42V63 BS88 Offset Tag Fuse?

The Mersen BTIS42V63 is a dependable BS88 gG offset tag fuse-link designed to protect industrial low-voltage electrical circuits against overloads and short circuits. It provides full-range circuit protection for cables, switchgear, distribution equipment and machinery used in demanding commercial and industrial installations.

As part of the established Mersen BTIS offset tag fuse-link range, the BTIS42V63 offers effective current-limiting performance, helping to reduce the thermal and mechanical stresses caused by high fault currents. Its robust construction supports reliable operation while helping protect valuable equipment and minimise unplanned downtime.

With a rated current of 63 A and voltage ratings of 415 V AC and 240 V DC, the BTIS42V63 is suitable for switchboards, distribution panels, industrial control systems and OEM machinery. Its offset tag format enables secure installation within compatible BS88 fuse holders and switch-disconnector assemblies.
