Why Choose the Mersen NH000AM50V50 NH Fuse Link?
The Mersen NH000AM50V50 is a compact NH000 size aM fuse link designed to provide reliable short-circuit protection for motors, motor starters and industrial electrical equipment. Rated at 50 A and 500 V AC, it is well suited to machinery, motor control centres and low-voltage power distribution systems.
Its aM operating characteristic allows the fuse to withstand the temporary inrush currents associated with motor starting while rapidly interrupting dangerous short-circuit currents. Because an aM fuse provides partial-range protection, the NH000AM50V50 should be used with a correctly selected overload relay or another suitable overload protection device.
The fuse link has a durable ceramic body, silver-plated copper blade contacts and live gripping tags for safe handling with an appropriate NH fuse puller. Its integrated double indicator helps maintenance personnel identify an operated fuse quickly, reducing diagnostic and replacement time.
Key Advantages
- Purpose-designed aM short-circuit protection for motor circuits.
- 50 A rated current for industrial motors and machinery.
- 500 V AC voltage rating for low-voltage installations.
- High 120 kA AC breaking capacity.
- Withstands normal motor starting and acceleration currents.
- Compact NH000 format saves space inside electrical panels.
Key Features
- Mersen NH industrial fuse-link range.
- NH000 standard fuse size.
- 50 A rated current.
- 500 V AC rated voltage.
- aM partial-range motor protection characteristic.
- 120 kA AC maximum breaking capacity.
- Integrated double fuse indicator.
- Live gripping tags for use with a compatible NH fuse puller.
- Silver-plated copper plain-blade terminals.
- Robust ceramic insulating body.
Reliable Short-Circuit Protection for Motor Circuits
Electric motors can draw several times their normal operating current during start-up. The Mersen NH000AM50V50 is designed to tolerate these temporary current surges while responding rapidly to severe short circuits. This helps protect motors, cables, contactors and associated switchgear from damaging thermal and electrodynamic effects.
As an aM fuse link, the NH000AM50V50 does not provide complete overload protection when used alone. It must be coordinated with a suitable thermal or electronic overload relay. Installation and replacement should only be carried out by qualified electrical personnel using an approved NH fuse puller and appropriate personal protective equipment.
Typical Applications
- Industrial motor starters and control panels.
- Motor control centres and switchgear assemblies.
- Pumps, fans and ventilation equipment.
- Conveyors and material handling machinery.
- Compressors and processing equipment.
- Manufacturing and production machinery.
