Fuse link - NH1 gS 315A/800V - ultra-fast / gS 004723237

Safety and reliability in electrical installations

NH1 gS 315A/800V fuse link is an element used to protect electrical circuits against overloads and short circuits. It is a key component in ensuring the safe and uninterrupted operation of installations, both in industrial and commercial applications. The construction based on ultra-fast (gS) technology ensures a quick response to current changes, minimizing the risk of equipment damage and power interruptions.

Characteristics and application

NH series fuse links are a proven standard in the protection of medium-voltage installations. The 315A/800V model, with gS characteristics, is designed to protect circuits with strong inrush currents, such as those occurring when starting electric motors or powering devices with high power consumption. The gS (ultra-fast) characteristic means that the fuse reacts very quickly to an increase in short-circuit current, which is particularly important in applications requiring a high level of safety. The top indicator allows for visual control of the insert status without the need for disassembly.

Construction and product features

The insert is designed to operate in alternating current (AC) circuits. Its rated current is 315A at a voltage of 800V AC. The lack of metal insulated grips (IMGL) simplifies the installation and replacement of the insert. The construction provides effective protection against the effects of overloads and short circuits - as can be expected from products of this type. It is worth noting the high short-circuit breaking capacity, which translates into increased installation safety and reduced energy losses. The size of the insert determines its physical dimensions and the range of rated currents with which it is compatible - this model belongs to the NH series.
