Why Choose the Mersen BTIA69V20M32 BS88 Offset Tag Motor Fuse?
The Mersen BTIA69V20M32 is a high-performance BS88 gM offset tag fuse-link designed to provide reliable short-circuit protection for industrial motors and associated electrical equipment. Its motor-duty operating characteristic withstands the temporary inrush currents generated during motor starting while rapidly interrupting dangerous fault currents.
As part of the established Mersen BTIA motor fuse-link range, the BTIA69V20M32 provides effective current limitation to reduce the thermal and mechanical stresses imposed on contactors, cables, switchgear and connected machinery during a short circuit. This helps improve installation safety, minimise equipment damage and support operational continuity.
Featuring a 20M32 motor fuse rating and voltage ratings of 690 V AC and 460 V DC, the BTIA69V20M32 is suitable for motor starters, motor control centres, industrial machinery and OEM control panels. Its offset tag configuration enables secure mounting in compatible BS88 fuse holders and switch-fuse assemblies.

Reliable Protection for Industrial Motor Circuits
The Mersen BTIA69V20M32 is engineered to protect motor circuits against high short-circuit currents while accommodating the elevated current drawn during normal motor acceleration. Its gM characteristic makes it suitable for use in coordinated motor protection systems alongside an appropriately selected overload relay or electronic motor protection device.
By limiting peak current and let-through energy during a fault, the fuse-link helps protect motor starters, contactors, cables and connected machinery. This can reduce repair costs, improve electrical safety and minimise production downtime in demanding industrial environments.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material-handling equipment.
- Industrial machinery and production lines.
