Why Choose the Mersen BTIS69V63 BS88 Offset Tag Fuse?

The Mersen BTIS69V63 is a high-performance BS88 gG offset tag fuse-link designed to provide dependable protection against overloads and short circuits in industrial low-voltage electrical systems. Its full-range operating characteristic makes it suitable for protecting cables, switchgear, distribution equipment and industrial machinery.

As part of the established Mersen BTIS offset tag fuse-link range, the BTIS69V63 delivers effective current-limiting performance that helps reduce the thermal and mechanical stresses caused by high fault currents. This supports improved equipment protection, greater installation safety and reduced disruption following an electrical fault.

With a rated current of 63 A and voltage ratings of 690 V AC and 460 V DC, the BTIS69V63 is suitable for demanding industrial power distribution applications. Its offset tag construction enables secure installation in compatible BS88 fuse holders, switch-fuse units and electrical distribution assemblies.

Key Advantages

  • Dependable BS88 gG industrial fuse-link for full-range circuit protection.
  • 63 A rated current for industrial power distribution systems.
  • 690 V AC and 460 V DC voltage ratings.
  • Current-limiting operation helps reduce damaging fault energy.
  • Offset tag format provides secure installation in compatible fuse equipment.
  • Suitable for switchboards, machinery, control panels and OEM systems.

Key Features

  • Mersen BTIS offset tag fuse-link series.
  • 63 A rated current.
  • 690 V AC / 460 V DC rated voltage.
  • gG general-purpose fuse characteristic.
