Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH3AM50V630P-2 incorporates an aM operating characteristic, providing dedicated short-circuit protection for motors and motor feeders. Because aM fuses are intended for motor applications, they are typically used alongside suitably rated overload relays to provide complete motor protection.
Its NH3 blade-contact construction enables installation into compatible NH fuse bases and fused switch-disconnectors. The integrated striker can activate auxiliary signalling or switching devices when the fuse operates, helping reduce downtime and improve maintenance efficiency.
Typical Applications
- Large industrial motors.
- Motor control centres.
- Industrial switchgear.
- Pump and compressor installations.
- Heavy-duty manufacturing equipment.
- Power distribution systems.
- Fuse switch-disconnectors with striker operation.
