Why Choose the Mersen NH0AM69V20 Motor Protection Fuse-Link?
The Mersen NH0AM69V20 is a high-performance DIN NH aM low voltage fuse-link specifically designed for short-circuit protection of motor circuits. Rated at 20 A and 690 V AC, this NH Size 0 fuse-link delivers dependable protection for motors, starters and associated control equipment operating in demanding industrial environments.
As part of Mersen's trusted NH aM fuse-link range, the NH0AM69V20 incorporates live gripping lugs with a double indicator, enabling safe handling using an approved fuse puller while providing clear visual indication when the fuse has operated. Manufactured in accordance with DIN NH and IEC standards, it offers high breaking capacity and reliable performance for industrial motor protection.
Unlike gG fuse-links, the aM operating characteristic is intended for motor circuit protection against short circuits only and should be used alongside an appropriate overload protection device, such as a thermal overload relay, to provide complete motor protection.
