£30.49
The Mersen BTCP42V100M125 is a British Standard BS88 gM offset bolted tag fuse-link specifically designed for motor circuit protection in low-voltage industrial electrical systems. Part of the trusted Mersen BTCP gM fuse-link range, it provides dependable short-circuit protection for motors while allowing the high inrush currents associated with motor starting.
Manufactured to EN 60269-2 and BS 88 Part 2, the BTCP42V100M125 features an offset bolted tag construction for secure installation into compatible fuse bases, switch disconnectors and motor control centres. Its gM operating characteristic is intended for motor circuits and should be used in conjunction with a suitable overload relay for complete motor protection.
With a 100M125 A motor rating, 415 V AC and 240 V DC voltage ratings, plus a high 80 kA AC and 40 kA DC breaking capacity, the Mersen BTCP42V100M125 is ideal for protecting industrial motors, motor starters and associated switchgear.
The Mersen BTCP42V100M125 is engineered for motor applications where high starting currents must be accommodated without nuisance operation. Its gM characteristic provides effective short-circuit protection while allowing normal motor acceleration, making it suitable for motor control centres, pumps, compressors, conveyors and other industrial machinery.
For complete motor protection, gM fuse-links should be coordinated with an appropriately selected thermal overload relay or motor protection device. This combination delivers comprehensive protection against both overload and short-circuit faults while maximising equipment reliability.
