Why Choose the Mersen NH1AM69V32 NH Fuse-Link?
The Mersen NH1AM69V32 is a high-quality NH size 1 aM fuse-link engineered to provide dependable short-circuit protection for industrial motors and associated electrical equipment. Rated at 32 A and 690 V AC, it is designed for use within low-voltage motor control centres, switchgear assemblies and industrial distribution systems.
Designed to the aM utilisation category, this fuse-link delivers partial-range protection specifically for motor circuits, offering excellent current limitation during fault conditions while requiring a coordinated overload relay for complete motor protection. Its robust ceramic construction, silver-plated copper contacts and double indication system ensure reliable operation in demanding industrial environments.
Manufactured to DIN NH standards, the NH1AM69V32 features live gripping lugs for safe handling using an approved NH fuse puller. Its standard NH1 format allows direct installation into compatible NH fuse bases and switch-fuse combinations used throughout industrial electrical installations.

Reliable Protection for Industrial Motor Circuits
The Mersen NH1AM69V32 is designed to rapidly interrupt high prospective fault currents before they can damage motors, contactors, cables and switchgear. Its current-limiting performance reduces thermal and mechanical stresses throughout the electrical installation, improving overall system reliability.
As an aM motor fuse-link, the NH1AM69V32 provides short-circuit protection only and must always be installed alongside a suitable overload relay or motor protection device to provide complete motor protection. Installation should be carried out by suitably qualified personnel using compatible NH fuse equipment.
