Why Choose the Mersen BTFP42V200M250 BS88 Offset Tag Fuse-Link?
The Mersen BTFP42V200M250 is a high-performance British Standard BS88 offset tag fuse-link designed for general-purpose motor protection (gM) in industrial low-voltage electrical systems. Part of the trusted Mersen BTFP series, this Type A4 fuse-link complies with EN 60269-2 Section II and BS88 Part 2, making it suitable for motor control centres, switchgear, distribution panels and OEM machinery.
Designed specifically for gM motor circuit protection, the BTFP42V200M250 provides excellent current limitation during short-circuit conditions whilst allowing the temporary inrush currents associated with motor starting. The offset tag construction enables secure installation in compatible BS88 fuse holders, fuse switch disconnectors or direct busbar-mounted assemblies.
With a 200M250 motor rating, 415 V AC and 240 V DC voltage ratings, this fuse-link offers dependable protection for industrial motors and associated electrical equipment in demanding applications.

Reliable Protection for Industrial Motor Circuits
The Mersen BTFP42V200M250 is engineered for motor applications where high starting currents are expected. Its gM operating characteristic allows temporary motor inrush currents while providing rapid interruption of short-circuit faults, helping to minimise damage to motors, cables, contactors and switchgear.
Its current-limiting design reduces thermal and mechanical stresses on downstream equipment, contributing to improved reliability and reduced downtime in industrial electrical installations.
Typical Applications
- Motor control centres.
- Industrial switchgear.
- Pump and compressor installations.
- Conveyor and processing equipment.
- OEM machinery.
- Industrial power distribution systems.
