Overview

The Mersen H227868 is a DIN NH Standard fuse-link, size NH00, designed for robust motor circuit protection. Rated for 690VAC and 125A, this 'aM' type fuse-link offers partial-range breaking capacity, making it ideal for short-circuit protection only. It is strongly current-limiting and features low power losses, with a body width of 30 mm. The double indicator provides clear visual status, and live gripping lugs ensure safe handling by qualified professionals. These fuse-links are part of the NH plug-in system, which includes a fuse-base, fuse-link with blade contact, and a fuse-link replacement device. Due to the system's design, non-interchangeability of rated current is not guaranteed, necessitating handling by trained personnel. The 'aM' designation signifies its suitability for motor circuits, interrupting currents from 6.3 times In up to its maximum breaking capacity. For overload protection, these fuse-links must be used in conjunction with other switchgear. This specific model (SKU: H227868) has a rated current of 125A and a power dissipation of 10W at In, with a package weight of 0.2 kg. Manufactured in France (FR), it adheres to IEC standards for low voltage fuse systems.
