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.

Reliable Protection for Industrial Motor Circuits
The Mersen BTC42V100M125 is designed to protect motor circuits against high short-circuit currents while tolerating the elevated current drawn during normal motor starting. Its gM characteristic is intended for use alongside a suitable overload protection device, such as a motor protection relay or thermal overload relay.
By limiting peak fault current and let-through energy, the fuse-link helps protect contactors, cables, motor starters and other downstream components. This supports improved electrical safety, reduced equipment damage and greater operational continuity in industrial installations.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Industrial machinery and production equipment.
- OEM control panels and switchboards.
