Fuse link - NH1 gG 160A/800V - time-lag 004184490

Safety and protection of electrical installations

NH1 gG 160A/800V fuse link is an element used to protect electrical circuits against overload and short circuit. It is designed to work with NH system fuse bases, ensuring reliable operation in various industrial and energy applications. Used in switchboards, control cabinets and other installations requiring high resistance to surge currents.

Characteristics and application

A gG (fully time-delay) fuse link is characterized by a delayed reaction to short-term current increases, which allows for the safe starting of devices with motors or other elements generating high inrush currents. This minimizes the risk of unnecessary circuit disconnection during normal operation. The rated current of 160A and the voltage of 800V AC make this fuse suitable for protecting circuits with medium and high power. It has a combined (double) operating indicator, which facilitates quick identification of a blown fuse.

Construction and mounting

The fuse link is made of high-quality materials, which guarantees its durability and reliability. Mounting is done in dedicated fuse bases of the NH system - both strip and box type. The lack of metal insulated grips (IMGL) means that the fuse link does not have additional insulation of the contacts, which is standard for this type of protection. It is important to select the correct fuse base, taking into account the rated current of the fuse link and the requirements of the installation.
