Knife fuse link NH000 double indicator non-insulated holder gG 63A 500VAC LNH0063M

Safety and protection of electrical installations

NH000 blade fuse link is an element used to protect electrical circuits against overloads and short circuits. This model, with a rated current of 63A and a voltage of 500VAC, is equipped with a double tripping indicator, which facilitates quick identification of a blown fuse. The design with an uninsulated holder is intended for use with appropriate fuse disconnectors.

Characteristics and application

The fuse link is characterized by a gG (formerly gL) characteristic, which means it is designed to protect general electrical installations and cables. Thanks to this, it provides effective protection against the effects of overloads and short circuits, protecting both devices and the installation. The front indicator allows for visual control of the fuse link status without the need to disconnect the circuit. The NH000 design makes it a popular solution in industrial installations and public buildings.

Construction and technical parameters

The fuse link is manufactured in accordance with IEC 60269 standard, which guarantees its high quality and reliability. Its dimensions (79 mm height, 20.8 mm width and 52.5 mm depth) allow for mounting in standard NH000 fuse disconnectors. The rated short-circuit switching capacity Icn is 80 kA (according to the manufacturer's data), which provides effective protection in the event of serious disturbances in the network. Total power loss at rated current is 3.4W. Made of halogen-free materials and compliant with REACh and RoHS – demonstrating care for the natural environment. Rated AC voltage is 690V.
