Why Choose the Mersen BTCP69V32M40 gM Motor Fuse Link?
The Mersen BTCP69V32M40 is an industrial gM motor fuse link designed to provide reliable short-circuit protection for electric motors, motor starters and associated power equipment. Manufactured by Mersen, it is engineered to withstand normal motor-starting currents while rapidly interrupting dangerous fault currents.
Its current-limiting operation helps reduce the peak current and total fault energy passed to cables, contactors, switchgear and downstream components during a short circuit. This can minimise thermal and mechanical damage, improve installation safety and reduce unplanned equipment downtime.
Featuring a 32 A continuous current rating, a 40 A motor circuit rating and a rated operating voltage of up to 690 V AC, the BTCP69V32M40 is suitable for coordinated motor protection systems in industrial control panels, motor control centres and machinery installations.

Reliable Short-Circuit Protection for Motor Circuits
Electric motors commonly draw several times their normal operating current during start-up. The Mersen BTCP69V32M40 is designed to accommodate this temporary inrush while responding rapidly to high-level short-circuit faults. This helps protect motor cables, contactors, starters and associated electrical equipment from excessive fault energy.
As a gM fuse link, the BTCP69V32M40 is primarily intended to provide short-circuit protection. It should normally be coordinated with a correctly selected overload relay, motor protection circuit breaker or equivalent device to provide comprehensive overload and fault protection for the motor circuit.
