Why Choose the Mersen NH000AM69V25 NH Fuse-Link?
The Mersen NH000AM69V25 is a high-performance NH aM low voltage fuse-link designed specifically for protecting motor circuits against short circuits in demanding industrial environments. Manufactured to DIN NH standards, this fuse-link delivers reliable fault protection while allowing motors to withstand their normal starting currents without unnecessary operation.
As part of the trusted Mersen NH aM 690 VAC fuse-link series, the NH000AM69V25 combines high current-limiting performance with a compact ceramic body and dependable fault interruption capability. The double indicator enables rapid identification of an operated fuse, while live gripping tags allow safer handling when used with an approved NH fuse puller.
With a rated current of 25 A and a 690 V AC operating voltage, this NH000 fuse-link is ideal for protecting motor starters, contactors, industrial machinery and motor control centres where dedicated overload protection is provided separately.

Reliable Protection for Industrial Motor Circuits
The Mersen NH000AM69V25 is designed specifically for motor circuit protection. Its aM operating characteristic provides rapid interruption of short-circuit faults while allowing the temporary high inrush currents generated during motor starting. Because it does not provide overload protection, it is intended for use alongside motor protection relays or thermal overload devices.
Its high current-limiting capability reduces thermal and mechanical stress on motors, cables and switching equipment during fault conditions. The standard NH000 format ensures compatibility with suitable NH fuse bases and switch-disconnectors used throughout industrial electrical installations.
Typical Applications
- Motor control centres.
- Industrial motor starters.
- Pump and fan control systems.
- Industrial machinery.
- Manufacturing equipment.
- OEM electrical panels.
- Low voltage industrial switchgear.
