Why Choose the Mersen BTC42V100 Fuse Link?

The Mersen BTC42V100 is a robust 100 A low-voltage fuse link designed to protect electrical distribution circuits and industrial equipment against overload and short-circuit currents. Manufactured by Mersen, it provides dependable circuit protection for installations where safe fault interruption and reliable long-term performance are essential.

The BTC42V100 uses current-limiting fuse technology to interrupt excessive current before it causes serious thermal or mechanical damage to cables, switchgear and connected equipment. Its durable construction makes it suitable for use in demanding commercial and industrial electrical environments.

With a rated current of 100 A and a rated voltage of 415 V AC, the BTC42V100 is suitable for compatible fuse holders, distribution boards, switchgear assemblies and control panels. It is an effective replacement fuse for electrical contractors, panel builders and maintenance engineers working with low-voltage power systems.
