Why Choose the Mersen NH2AM69V100 NH Fuse-Link?
The Mersen NH2AM69V100 is a high-performance DIN NH aM fuse-link designed to provide reliable short-circuit protection for motors, motor starters and associated industrial equipment. As part of the trusted Mersen NH aM 690 V AC fuse-link series, it delivers dependable protection for motor circuits operating in demanding industrial environments.
Manufactured in accordance with DIN NH and IEC standards, this NH2 size fuse-link features double visual indicators and live gripping lugs, allowing rapid identification of an operated fuse and safer replacement by qualified personnel. Its ceramic body and current-limiting construction help minimise thermal and mechanical stresses during fault conditions.
With a 100 A rated current, a 690 V AC rated operating voltage and an 80 kA AC breaking capacity, the NH2AM69V100 is intended for motor circuit short-circuit protection where overload protection is provided separately by a motor protection relay or circuit breaker.
