Overview

The Mersen A227884 is a DIN NH Standard fuse-link, specifically an aM type, designed for motor circuit protection. Rated for 500VAC and 200A, this NH0 size fuse-link features double indicators and live gripping tags for enhanced safety and visibility. Its body width is 30mm. As part of the NH system, which is classified among plug-in fuse systems, it comprises a fuse-base, fuse-link with blade contact, and a fuse-link replacement device. The 'aM' designation signifies partial-range breaking capacity, making these fuse-links ideal for short-circuit protection of motor circuits due to their strong current-limiting capabilities and low power losses. They are engineered to interrupt currents from 6.3 times the rated current up to their maximum breaking capacity. It is crucial to note that due to the design of the NH system, which cannot guarantee non-interchangeability of rated current, these fuse-links must be handled by a qualified professional. For overload protection, these fuse-links must be used in conjunction with other switchgear. The rated current of these fuse-links can be equal to the motor's nominal current. This specific model, SKU A227884, manufactured by Mersen in France, offers reliable protection for industrial motor applications where precise short-circuit interruption is paramount.
