Fuse link - NH2C gG 125A/500V - time-lag 004185215

Installation and device safety – NH2C fuse links

NH2C gG 125A/500V fuse link is a reliable protection against the effects of overloads and short circuits in electrical installations. Designed for use with switchgear and industrial circuits, it provides effective protection of wires and devices. Manufactured by the renowned ETI Polam, it meets the requirements of IEC 60269-1 and IEC 60269-2 standards, guaranteeing safety and compliance with applicable regulations.

Construction and operation

The fuse link is characterized by a time-delay gG characteristic, which means that it allows for short-term exceeding of the rated current without disconnecting the circuit. This is particularly important when starting devices with electric motors, which generate high starting currents. The fuse body is made of durable steatite, and the knife contacts are silver-plated to ensure low resistance and minimize power losses. The fuse has a double tripping indicator – a red eye on the ceramic body and a springy plate on the top cover – which facilitates quick identification of a blown fuse. This combined signaling system is particularly useful in fuse disconnectors and in situations where access to the fuse is difficult.

Key features and benefits

• Full-range protection (gG): Protects against overloads and short circuits, providing comprehensive protection of the installation.
• Time-delay characteristic: Allows for trouble-free starting of devices with electric motors without unnecessary disconnection of the circuit.
• Double tripping indicator: Facilitates quick identification of a blown fuse, reducing installation downtime.
• High breaking capacity (120 kA): Ensures effective interruption of short-circuit current, minimizing the risk of damage to equipment and installations.
• Made of high-quality materials: Guarantees durability and reliable operation in harsh industrial conditions.
• Manufactured in the EU: Confirms compliance with European standards of quality and safety.
• Size NH2C: Standard size of fuse links, ensuring compatibility with a wide range of switchgear and fuse boxes.

Applications

NH2C gG 125A/500V fuse links are used in:

• Industrial installations
• Low-voltage switchgear
• Power circuits for electric motors
• Systems for protection against overloads and short circuits
• Protection of electrical wires

Thanks to their reliability and high technical parameters, they are an ideal solution for demanding industrial applications and commercial construction. It is important to remember to select the correct fuse link for a specific application, taking into account the rated current of the circuit and the expected short-circuit currents.
