Mersen NH4AAM69V630-8

The NH fuse-link system is categorized as a plug-in fuse system, consisting of essential components including the fuse-base, which may include terminal covers and phase barriers, as well as the fuse-link itself with blade contact. A fuse-link replacement device, specifically a low-voltage HRC fuse puller, is also part of this setup. Type aM NH fuse-links are recognized for their partial-range breaking capacity, specifically designed to safeguard motor circuits due to their strong current-limiting capabilities and minimal power losses.

These fuse-links are capable of interrupting currents that are 6.3 times the rated current (In) up to their maximum breaking capacity, making them suitable exclusively for short-circuit protection. For effective overload protection, these fuse-links should be paired with additional switchgear. Notably, the rated current of these fuse-links can match the nominal current of the motor they protect.

Constructed from materials such as copper and silver-plated contacts, the fuse-links are compliant with ROHS standards, with a ceramic body style that adheres to various industry standards including DIN 57636 Part 201, VDE 0636 Part 201, and IEC 60269-1 and -2. The ampere range spans from 400 to 1000 A, ensuring versatility in motor circuit applications.
