Why Choose the Mersen NH000AM50V10 Motor Protection Fuse-Link?
The Mersen NH000AM50V10 is a compact DIN NH aM low-voltage fuse-link designed specifically to provide short-circuit protection for industrial motor circuits. Rated at 10 A and 500 V AC, this NH Size 000 fuse-link helps protect motors, contactors, starters, cables and associated switching equipment against damaging fault currents.
Its aM partial-range operating characteristic provides strong current-limiting performance while allowing the temporary inrush currents associated with motor starting. The fuse-link interrupts currents from approximately 6.3 times its rated current up to its maximum breaking capacity, making it suitable for short-circuit protection rather than overload protection.
The NH000AM50V10 features a compact ceramic body, silver-plated copper blade contacts, live gripping lugs and a double indication system. These features support reliable installation in compatible NH000 fuse bases while enabling quick visual identification after the fuse has operated.
Key Advantages
- Designed specifically for motor circuit short-circuit protection.
- 10 A rated current for industrial motor applications.
- 500 V AC rated voltage for low-voltage motor systems.
- High 120 kA AC breaking capacity.
- Current-limiting operation helps reduce thermal and mechanical fault stress.
- Double indicator enables rapid identification of an operated fuse.
- Compact NH000 format supports space-efficient panel installation.
Key Features
- Mersen NH aM 500 V AC fuse-link range.
- Catalogue reference: NH000AM50V10.
- Manufacturer item number: N232496.
- 10 A rated current.
- 500 V AC rated voltage.
- NH Size 000 construction.
- aM partial-range motor protection characteristic.
- Double indication system.
- Live, non-isolated gripping lugs.
- Silver-plated copper blade contacts.
Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH000AM50V10 rapidly limits and interrupts high fault currents before they can cause serious damage to motor starters, contactors, cables or connected equipment. Its current-limiting action reduces the energy passed through the circuit during a fault, helping improve equipment protection and system reliability.
Because this is an aM partial-range fuse-link, it does not provide protection against sustained motor overloads. It must therefore be coordinated with a correctly selected thermal overload relay, electronic overload device or motor protection circuit breaker to provide complete motor circuit protection.
Typical Applications
- Industrial motor control centres.
- Direct-on-line motor starters.
- Star-delta starter circuits.
- Pumps, fans and conveyor systems.
- Manufacturing and processing machinery.
- Industrial automation and control panels.
