Reliable Protection for Industrial Motor Circuits
The Mersen NH2AM69V355 has been developed for industrial motor applications where high inrush currents occur during motor starting. Its aM operating characteristic permits these temporary starting currents while rapidly clearing high fault currents that could damage motors, contactors and associated switchgear.
As an aM fuse-link, the NH2AM69V355 provides short-circuit protection only and should be used alongside an appropriate overload relay or motor protection device to provide complete motor protection.
Typical Applications
- Motor control centres.
- Industrial motor starter circuits.
- Large electric motors.
- Pumps, compressors and conveyors.
- Industrial switchboards.
- OEM machinery and power distribution equipment.
