Why Choose the Mersen BTC42V100M125 BS88 Centre Tag Fuse?
The Mersen BTC42V100M125 is a robust BS88 gM centre tag fuse-link designed to provide dependable short-circuit protection for industrial motor circuits. Its motor-rated operating characteristic accommodates the temporary inrush currents generated during motor starting while rapidly interrupting dangerous fault currents.
As part of Mersen’s industrial fuse-link range, the BTC42V100M125 provides effective current limitation to reduce the thermal and mechanical stresses placed on cables, switchgear and connected equipment during a short circuit. Its durable construction supports reliable operation in demanding motor control and power distribution environments.
Featuring a 100M125 motor fuse rating and voltage ratings of 415 V AC and 240 V DC, the BTC42V100M125 is suitable for motor control centres, industrial switchboards, machine control panels and OEM equipment. The centre tag format enables secure mounting in compatible BS88 fuse holders and switch-fuse assemblies.
