Reliable Short-Circuit Protection for Motor Applications
The Mersen NH0AM69V50 is designed to protect industrial motor circuits by interrupting high fault currents while allowing the temporary inrush currents that occur during normal motor starting. This helps minimise damage to motors, starters and associated electrical equipment, reducing downtime and maintenance costs.
As an aM partial-range fuse, the NH0AM69V50 is intended to be used in conjunction with an appropriate motor overload relay or motor protection circuit breaker to provide complete motor circuit protection.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Industrial pumps and compressors.
- Conveyor systems.
- Manufacturing and processing machinery.
- Electrical distribution and control panels.
