Why Choose the Mersen NH1AM69V200P-2 NH Fuse Link?
The Mersen NH1AM69V200P-2 is a high-performance NH1 aM fuse link designed to provide dependable short-circuit protection for motors and industrial power circuits. As part of Mersen’s range of DIN NH standard fuse links, it offers strong current-limiting performance and low power losses in demanding motor control and electrical distribution applications.
With a rated current of 200 A and an operating voltage of up to 690 V AC, the NH1AM69V200P-2 is suitable for high-power machinery, motor control centres and industrial switchgear. Its robust ceramic body, silver-plated copper contacts and high breaking capacity support reliable operation under severe electrical fault conditions.
The integrated striker indication system can activate a signalling device or compatible switch mechanism when the fuse operates. Its standard NH1 blade-contact format enables installation in suitable fuse bases and switch-fuse assemblies, while the live gripping tags must be handled by appropriately qualified personnel using approved equipment.

Reliable Short-Circuit Protection for Motor Circuits
Type aM fuse links are partial-range fuses specifically developed for the short-circuit protection of motors and associated electrical equipment. Their strong current-limiting characteristics help reduce the thermal and mechanical stress placed on contactors, cables, motor starters and other components during a fault.
The Mersen NH1AM69V200P-2 must be used with a suitable overload protection device, such as a motor protection relay or circuit breaker, because an aM fuse does not provide full-range overload protection. This coordinated arrangement delivers effective motor circuit protection while accommodating the temporary starting currents produced by industrial motors.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps, compressors and ventilation systems.
- Conveyors and material handling machinery.
- Manufacturing and processing equipment.
- Industrial switchgear and fuse disconnectors.
- High-power machinery and automation systems.
