Why Choose the Mersen NH2AM69V80 NH Fuse-Link?
The Mersen NH2AM69V80 is a premium DIN NH aM fuse-link designed to provide dependable short-circuit protection for motors and motor control circuits in demanding industrial environments. As part of the trusted Mersen NH aM 690 V fuse-link series, it combines excellent current-limiting performance with robust construction to protect motors, contactors and associated electrical equipment.
Featuring an aM operating characteristic, this fuse-link is specifically engineered for motor circuit protection. It is designed to withstand the high inrush currents associated with motor starting whilst rapidly interrupting damaging short-circuit currents. As an aM fuse-link provides partial-range protection, it must be used together with a suitable overload relay or motor protection device.
With a rated current of 80 A, a rated voltage of 690 V AC, an NH2 fuse size and a body width of 52 mm, the NH2AM69V80 is ideal for motor starters, motor control centres, industrial machinery and OEM electrical panels requiring reliable motor circuit protection.
