Why Choose the Mersen BTF42V200M315 BS88 gG Fuse Link?
The Mersen BTF42V200M315 is a high-current British Standard BS88 gG fuse link designed to protect industrial and commercial electrical systems against overload and short-circuit currents. Manufactured by Mersen, it provides effective current limitation to help safeguard cables, conductors, switchgear and connected equipment during severe electrical fault conditions.
Its gG full-range operating characteristic enables the BTF42V200M315 to respond to sustained overload currents as well as high-level short circuits. The robust ceramic body and bolted-tag terminal arrangement provide secure mechanical and electrical connections within compatible fuse holders, fuse switches and low-voltage distribution assemblies.
With a rated current of 315 A and a rated operating voltage of up to 415 V AC, the Mersen BTF42V200M315 is suitable for switchboards, industrial machinery, distribution panels and infrastructure applications requiring dependable high-current circuit protection.
