Fuse link - NH1 gG 100A/800V - time-lag 004184488

Safety and electrical installation protection

NH1 fuse link with a rated current of 100A and a voltage of 800V is a key protective element in electrical installations. Designed for use with alternating current (AC) circuits, it provides effective protection against overloads and short circuits. The gG (time-delay) characteristic means that the fuse link reacts with a delay to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high starting currents. This minimizes the risk of unnecessary circuit tripping during normal operation.

Construction and application

The NH1 fuse link manufactured by ETI POLAM belongs to the WT-NH series. Its construction based on the NH1 standard guarantees compatibility with dedicated fuse holders. The combined (double) operating indicator facilitates quick identification of a blown fuse link, which speeds up the process of locating and repairing faults. It finds application in electrical switchboards, control cabinets and other installations requiring reliable protection against the effects of short circuits and overloads.

Key features and benefits

• High reliability: Ensured by the reputable manufacturer – ETI POLAM – and compliance with safety standards.
• Protection against overloads and short circuits: Protects devices and electrical installations from damage caused by excessive load or short circuit.
• Time-delay characteristic (gG): Allows for trouble-free starting of devices with high inrush currents, such as electric motors, without triggering the protection.
• Operating indicator: Facilitates quick identification of a blown fuse link, reducing installation downtime.
• Versatility: Designed for use in a wide range of industrial and commercial applications.
• Safety: Ensures safe operation of the electrical installation, minimizing the risk of fire or electric shock.
• Metal insulated grips (IMGL) absent: Absence of metal insulated grips provides additional safety during fuse replacement.
