£33.07
The Mersen BTC42V100M200 is a high-performance British Standard BS88 gM motor protection fuse link engineered to provide reliable short-circuit protection for industrial motors, motor starters and associated electrical equipment. Manufactured by Mersen, this central bolted fuse link is designed specifically for motor circuits where high starting currents must be accommodated while maintaining rapid fault interruption.
Manufactured in accordance with EN 60269-2 and BS 88 Part 2, the BTC42V100M200 delivers excellent current-limiting performance to minimise fault energy and protect electrical installations. Its central bolted tag design provides a secure connection for installation in compatible fuse holders, switch-fuse units and disconnectors.
With a 415 V AC / 240 V DC rating and a 100M200 motor rating, this fuse is ideal for industrial motor circuits, control panels, distribution equipment and machinery where dependable motor protection and high breaking capacity are essential.
Motor protection fuse links are designed to withstand the high inrush currents generated during motor starting while providing rapid interruption of severe fault currents. The Mersen BTC42V100M200 offers effective coordination with motor starters and overload relays, helping protect motors, cables and switchgear from catastrophic short-circuit conditions.
Its high breaking capacity and current-limiting performance make it suitable for demanding industrial environments where electrical reliability and equipment protection are critical.
