Fuse link - NH2 gG 40A/500V - time-lag 004185236

Installation and device safety – NH2 fuse links

NH2 gG 40A/500V fuse link is an element used to protect electrical installations from the effects of overloads and short circuits. Designed for use in industrial circuits, it provides reliable protection of wires and devices. The version with gG characteristic, i.e. for general purpose, will work in a wide range of applications.

This fuse link is characterized by a rated current of 40A and a rated voltage of 500V AC. Manufactured by the renowned manufacturer ETI Polam, it meets the requirements of IEC 60269-1 and IEC 60269-2 standards, guaranteeing safety and compliance with applicable standards. Its construction based on steatite and silver-plated brass contacts ensures thermal stability and minimizes the risk of corrosion.

Key features for professionals:

• Dual tripping indicator (KOMBI): Allows quick and reliable identification of a blown fuse – both visually on the top cover and through the red eye on the ceramic body. This facilitates diagnostics and reduces installation downtime.
• High short-circuit breaking capacity (120kA): Provides effective protection against the effects of serious short circuits, minimizing the risk of damage to the installation and equipment.
• Made of high-quality materials: Steatite body and silver-plated brass contacts guarantee durability and reliability in harsh industrial conditions.
• Compliance with standards: Meeting the requirements of IEC 60269-1 and IEC 60269-2 confirms safety of use and compliance with applicable regulations.

Practical advantages for the end user:

• Protection against failures: The fuse link protects electrical devices from damage caused by overload or short circuit, which translates into financial savings and avoidance of unplanned downtime.
• Safety of use: Provides protection of people against electric shock in the event of a failure of the installation.
• Long service life: The use of high-quality materials guarantees long-term operation of the fuse link without the need for frequent replacement.
• Easy identification of a blown fuse: The dual tripping indicator makes it easy to quickly locate the damaged element, reducing repair time.

Additionally, filling the body with special quartz sand stabilizes the electrical parameters of the fuse link and increases its breaking capacity. It is also worth noting the unified NH2 size designation, which replaces the older WT-2 designation – this makes it easier to select the appropriate replacement if a replacement is needed.
