Why Choose the Mersen BTIA55V20M32 Motor Circuit Fuse Link?
The Mersen BTIA55V20M32 is an industrial motor circuit fuse link designed to provide dependable short-circuit protection for electric motors, motor starters and associated control equipment. Manufactured by Mersen, it combines effective fault-current limitation with operating characteristics suited to circuits that experience high starting currents.
Unlike a general-purpose fuse, the BTIA55V20M32 is designed to tolerate the temporary current surge produced during normal motor starting. This helps prevent unnecessary fuse operation while ensuring rapid circuit interruption if a severe electrical fault occurs.
With a 20M32 motor fuse rating and a rated operating voltage of up to 550 V AC, the BTIA55V20M32 is suitable for industrial machinery, motor control centres and three-phase motor installations. Its offset-tag construction enables secure installation in compatible BS88 fuse holders, fuse-switch disconnectors and motor control assemblies.
Key Advantages
- Industrial motor circuit fuse link for dependable short-circuit protection.
- 20M32 motor fuse rating suitable for circuits with elevated motor starting currents.
- 550 V AC voltage rating for industrial motor and machinery applications.
- Helps prevent nuisance operation during normal motor acceleration.
- Current-limiting performance helps reduce damaging fault energy.
- Designed for use alongside contactors and motor overload protection devices.

Reliable Protection for Industrial Motor Circuits
The Mersen BTIA55V20M32 protects motor circuits by rapidly interrupting high short-circuit currents before they can cause serious damage to cables, contactors, switchgear or motor windings. Its current-limiting action helps reduce the thermal and mechanical stresses produced during electrical faults.
The fuse link should normally be coordinated with a correctly selected motor overload relay or electronic motor protection device. The overload device protects against sustained overcurrent conditions, while the BTIA55V20M32 provides fast interruption of severe short-circuit faults.
Typical Applications
- Three-phase industrial motor circuits.
- Motor control centres.
- Direct-on-line and contactor motor starters.
- Industrial pumps, fans and compressors.
- Conveyors and production machinery.
- OEM automation and electrical control panels.
