Why Choose the Mersen NH2AM50V315 Motor Protection Fuse-Link?
The Mersen NH2AM50V315 is a high-performance NH2 aM fuse-link specifically designed for the short-circuit protection of motors, motor starters and associated electrical equipment. Manufactured to the DIN NH standard, it provides outstanding current-limiting performance whilst safely withstanding the high inrush currents produced during motor starting.
Rated at 315 A with a 500 V AC operating voltage, the NH2AM50V315 forms part of Mersen's proven aM motor protection range. The aM operating characteristic provides short-circuit protection only and should always be used alongside an appropriately selected overload relay or motor protection device to provide complete motor protection.
The fuse-link incorporates live gripping tags, a double visual indicator, silver-plated copper blade contacts and a robust ceramic body. With a 120 kA AC breaking capacity, it delivers dependable protection for motor control centres, industrial switchboards and OEM machinery.

Reliable Short-Circuit Protection for Industrial Motor Circuits
The NH2AM50V315 is designed for high-power motor applications where substantial starting currents occur. Its aM characteristic allows the fuse-link to withstand temporary inrush currents whilst providing rapid interruption during short-circuit faults, helping minimise damage to motors, starters and associated electrical equipment.
As an aM fuse-link provides short-circuit protection only, it should always be combined with a correctly selected overload relay or motor protection device to provide complete protection for the motor installation.
