Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH000AM69V63 is designed specifically for protecting motors and motor starters against high fault currents. Its aM characteristic allows normal motor starting currents to pass without nuisance operation whilst rapidly interrupting damaging short circuits, helping maximise motor reliability and minimise production downtime.
As an aM fuse link, the NH000AM69V63 provides partial-range protection and should be used alongside an appropriate overload relay or motor protection device to provide complete motor protection.
Typical Applications
- Motor control centres (MCCs).
- Direct-on-line motor starters.
- Star-delta motor starters.
- Industrial switchboards.
- OEM machinery and automation systems.
- Pumps, fans, compressors and conveyor systems.
