Why Choose the Mersen BTIS69V32M50 Motor Circuit Fuse Link?
The Mersen BTIS69V32M50 is an industrial motor circuit fuse link designed to provide dependable short-circuit protection for motors, motor starters and associated electrical equipment. Manufactured by Mersen, it offers effective current limitation and reliable fault interruption for demanding industrial power and automation systems.
The BTIS69V32M50 is specifically suited to motor applications where high starting currents must be tolerated without unnecessary fuse operation. Its motor-rated time-current characteristics allow normal motor acceleration while providing rapid disconnection during potentially damaging short-circuit conditions.
With a 32M50 motor fuse rating and an operating voltage of up to 690 V AC, the BTIS69V32M50 is suitable for use in motor control centres, industrial machinery and three-phase motor installations. Its industrial tag construction enables secure installation within compatible fuse holders, fuse-switch disconnectors and motor control assemblies.

Reliable Protection for Industrial Motor Circuits
Motor circuit fuse links such as the Mersen BTIS69V32M50 are designed to withstand the temporary inrush currents produced when an electric motor starts. This helps avoid unnecessary fuse operation while maintaining rapid and effective protection against high short-circuit currents.
The fuse link is normally used alongside a correctly selected motor overload relay or motor protection device. The overload device protects against sustained overload conditions, while the BTIS69V32M50 provides high-speed interruption of severe electrical faults within the motor circuit.
Typical Applications
- Three-phase industrial motor circuits.
- Motor control centres.
- Motor starters and contactor assemblies.
- Industrial pumps, fans and compressors.
- Conveyors and production machinery.
- OEM automation and electrical control panels.
