Knife fuse link NH000 double indicator non-isolated holder aM 20A 690VAC LNH000020M6A

Safety and Reliability in Electrical Installations

This NH000 fuse link is a key element ensuring protection against overloads and short circuits in electrical circuits. Designed to operate in AC systems with a rated voltage of 690V, it is perfect for protecting electric motors thanks to its aM characteristic (motor short-circuit protection). The combined indicator (double) facilitates quick identification of a blown fuse, significantly reducing diagnosis and repair time.

Design and Application

The NH000 fuse link with a rated current of 20A, manufactured in accordance with IEC 60269, is intended for mounting in dedicated knife holders. Its construction provides effective protection of the electrical installation, minimizing the risk of damage and downtime. Power loss at rated current is only 1W, which translates to efficient energy use. The absence of metal insulated grips (IMGL) simplifies installation and removal.

Key Features and Benefits

• Motor Protection: The aM characteristic provides optimal protection for electric motors against the effects of short circuits, allowing for a quick response to sudden load changes.
• Blown Fuse Indicator: The double operation indicator facilitates visual identification of a blown fuse – saving time and eliminating the need to check each circuit.
• Versatility: Designed for operation in 690V AC systems, making it compatible with a wide range of electrical installations.
• High Quality: Compliance with IEC 60269 guarantees reliable operation and long product life.
• Practical Packaging: Available in packs of 3, making it easier to replenish stocks and reduce costs.
• Rated Breaking Capacity: Ensures safe disconnection of the circuit in the event of a short circuit thanks to a high rated short-circuit breaking capacity of 80kA.
• Compact Dimensions: Height 79mm, width 21mm and depth 51mm allow for easy installation even in limited space.
