Why Choose the Mersen NH1AM69V100 Motor Protection Fuse-Link?
The Mersen NH1AM69V100 is a high-performance NH1 aM fuse-link engineered specifically for the short-circuit protection of motors, motor starters and associated electrical equipment. Manufactured to the DIN NH standard, it delivers excellent current-limiting performance whilst withstanding the high inrush currents generated during motor starting.
Rated at 100 A with a 690 V AC operating voltage, the NH1AM69V100 belongs to Mersen's aM motor protection fuse range. The aM operating characteristic is intended for short-circuit protection only and should always be used alongside an appropriate thermal overload relay or motor protection device to provide complete motor protection.
The fuse-link incorporates live gripping tags, a double visual indicator, silver-plated blade contacts and a durable ceramic body. Designed for installation in compatible NH1 fuse bases and fuse-switch disconnectors, it provides dependable protection for industrial motor circuits, MCCs and OEM machinery.

Reliable Short-Circuit Protection for Motor Circuits
The NH1AM69V100 is specifically designed for motor circuits where high starting currents occur. Its aM characteristic allows the fuse-link to withstand temporary motor inrush currents whilst providing rapid interruption during short-circuit faults, helping minimise damage to motors, starters and associated electrical equipment.
As an aM fuse-link provides short-circuit protection only, it must always be used together with a correctly selected overload relay or motor protection device to provide complete protection for the motor.
Typical Applications
- Motor starters.
- Motor control centres.
- Industrial motor circuits.
- Pump and fan control panels.
- OEM machinery.
- Industrial switchboards.
- HVAC equipment.
- Manufacturing automation systems.
