Why Choose the Mersen BTIA42V32M63 BS88 gM Fuse Link?
The Mersen BTIA42V32M63 is a robust BS88 gM offset tag fuse link designed to provide dependable short-circuit protection for electric motors and industrial motor circuits. Manufactured by Mersen, it combines a compact industrial format with high fault-current interruption performance for demanding electrical installations.
As a motor-rated gM fuse link, the BTIA42V32M63 is engineered to tolerate the temporary inrush currents that occur when motors start while rapidly interrupting dangerous short-circuit currents. This operating characteristic makes it suitable for use alongside correctly selected overload protection within motor starters, control panels and motor control centres.
The fuse has a 32 A continuous current rating, a 63 A motor circuit rating and a rated operating voltage of up to 415 V AC. Its offset tag construction provides secure mechanical and electrical connection within compatible BS88 fuse holders, fuse switches and switch-disconnectors.
Key Advantages
- Purpose-designed gM fuse link for industrial motor circuits.
- 32 A continuous current rating with a 63 A motor circuit designation.
- 415 V AC voltage rating for low-voltage industrial systems.
- Allows normal motor starting currents without unnecessary fuse operation.
- Provides fast, current-limiting protection during short-circuit conditions.
- Offset tag format supports secure installation in compatible BS88 fuse equipment.

Reliable Short-Circuit Protection for Motors
Electric motors can draw several times their normal operating current during start-up. The Mersen BTIA42V32M63 is designed to withstand these temporary starting currents while providing rapid interruption when a genuine short circuit occurs. This helps protect cables, contactors, switchgear and motor circuits from damaging fault energy.
Because a gM fuse is primarily intended for short-circuit protection, it is normally coordinated with a suitable overload relay or motor protection device. Correct coordination provides comprehensive protection against both prolonged overloads and high-level electrical faults.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Manufacturing and processing machinery.
- Industrial switchboards and control panels.
