Fuse link - NH1 gG 125A/800V - time-lag 004184489

NH fuse links – reliable installation protection

NH1 gG 125A/800V fuse link is an element used to protect electrical circuits against overload and short circuit. It is characterized by a time-delay characteristic, which means that it allows for short-term exceedances of the rated current without disconnecting the circuit – an ideal solution for devices with motors or other loads generating high starting currents. Made of high-quality materials, it ensures long-lasting and reliable operation.

Construction and application

NH series fuse links are a proven standard in the protection of medium-voltage installations. The construction based on a body made of ceramics or melamine, filled with quartz sand, guarantees effective extinguishing of the electric arc in the event of a failure. Model NH1 is designed to work with dedicated fuse holders, allowing for safe and convenient replacement if necessary. Widely used in low-voltage switchboards, control cabinets, and in industrial and construction installations.

Key features and benefits

• Time-delay characteristic (gG): Allows for momentary overloads, minimizing the risk of unnecessary circuit disconnection during device startup with high current draw.
• High breaking capacity: Ensures effective protection against the effects of short circuits and overloads, protecting devices and electrical installations from damage.
• Rated voltage 800V AC: Enables use in a wide range of electrical installations.
• Rated current 125A: Suitable for protecting circuits with medium load.
• Operation indicator: Combined (double) indicator facilitates visual identification of the fuse status – whether it has blown or not.
• Without metal isolating clips (IMGL): Increases safety and facilitates installation.
• Compliant with IEC 60269 standard: Guarantee of safety and quality confirmed by a certificate of conformity with applicable standards.

It is important to remember that proper selection of the fuse link for a specific application is crucial to ensure optimal protection of the electrical installation. The selection should take into account the rated current of the circuit, expected starting currents, and operating conditions.
