Why Choose the Mersen NH2AM69V315P-2 NH Fuse Link?
The Mersen NH2AM69V315P-2 is a high-performance NH2 aM low-voltage fuse link designed specifically for short-circuit protection of motors, motor starters and industrial power circuits. Manufactured to DIN NH standards, this partial-range fuse link delivers excellent current limitation and dependable interruption of high fault currents while allowing normal motor starting currents.
With a rated current of 315 A and a rated operating voltage of 690 V AC, the NH2AM69V315P-2 is ideally suited for industrial motor feeders, switchgear and machine control systems. Its aM operating characteristic is intended for short-circuit protection only and should always be used together with a suitable overload relay or motor protection circuit breaker.
The fuse link incorporates live gripping lugs, silver-plated copper blade contacts, a durable ceramic body and an integrated mechanical striker for fuse indication and auxiliary switching functions. It is designed for installation in compatible NH fuse bases and switch-fuse disconnectors used throughout industrial low-voltage power distribution systems.
