Fuse link - NH3 gG 160A/800V - time-lag 004184524

Safety and protection of electrical installations – NH fuse links

NH3 gG 160A/800V fuse link is an element used to protect electrical circuits against overload and short circuit. This is particularly important in industrial installations and public buildings, where high reliability and safety are required. NH fuse links are characterized by a high short-circuit breaking capacity, which minimizes the risk of damage to equipment and installations.

Characteristics and application

This specific fuse link, with a time-delay characteristic (gG), is designed to protect circuits with elements with high inrush current – motors, transformers or other inductive devices. The gG characteristic allows for short-term exceeding of the rated current without tripping, which is crucial for the proper operation of these devices. The combined (double) tripping indicator provides both a quick response in the event of a short circuit and a delayed response to short-term overloads.

Construction and parameters

The fuse link is designed for AC 800V voltage and a rated current of 160A. The lack of metal insulated grips (IMGL) means a standard construction, compatible with most available NH3 fuse holders. It is worth noting the versatility of this solution – NH3 fuse links are widely used in low-voltage switchboards and control cabinets. This makes replacing a damaged fuse link simple and does not require specialized tools or knowledge.

• Provides protection against overload in electrical installations.
• Reacts quickly to short circuits, protecting against fire and failures.
• Thanks to the time-delay characteristic (gG), it is ideal for circuits with motors and other inductive devices.
• Has a tripping indicator to facilitate identification of a blown fuse and location of the fault.
• Compatible with a wide range of available fuse holders thanks to the standard NH3 size.
