NH Fuse Links – Reliable Installation Protection

NH1C gG 20A/500V fuse links are used to protect cables and wires against the effects of overloads and short circuits in industrial and building installations. They are widely used where solid protection of electrical circuits is required. A construction based on proven materials and compliance with industry standards guarantee reliable operation and long service life.

Characteristics and application

NH1C fuse links with gG characteristics (time-delay) are designed for general use, providing comprehensive protection against overloads and short circuits. The time-delay characteristic means that the fuse link reacts with a certain delay to short-term current surges, which is particularly important when starting devices with electric motors or other loads with high inrush current. This avoids unnecessary tripping of the circuit during normal operation. The rated current of 20A and the rated voltage of 500V AC make this fuse link suitable for a wide variety of installations.

Advantages and product features

• Dual tripping indicator: Equipped with a red eyelet located in the central part of the ceramic body and a spring-loaded plate on the top cover, provides easy and unambiguous visual identification of fuse failure – both in the fuse base and in the disconnector.
• High breaking capacity: The rated short-circuit breaking capacity AC is as high as 120kA, which guarantees effective interruption of the circuit in the event of a serious short circuit.
• Solid construction: The body made of steatite (thermally stable material) and silver-plated knife contacts ensure durability and corrosion resistance. Filling with quartz sand stabilizes the electrical parameters.
• Compliance with standards: The fuse links meet the requirements of IEC 60269-1 and IEC 60269-2 standards, confirming their safety and quality.
• Versatile application: Ideal for protecting electrical installations in industry, construction and other public facilities.
• Indicator compatible with signaling: The indicator on the top cover enables cooperation with the NVS 5 microswitch for remote signaling of fuse link operation.
• Rated current: 20A provides adequate protection for many typical electrical circuits.
