NH Fuse Links – Reliable Installation Protection

NH knife-type fuse links are a proven element of electrical protection, designed to protect against the effects of short circuits and overloads. The design and parameters of these fuse links comply with PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, which guarantees their reliable operation and safety. The NH3C gG 160A/500V model, thanks to its time-delay characteristic (gG), is perfect for circuits requiring tolerance to short-term overvoltages, such as those occurring during motor starting.

Construction and application

NH fuse links are characterized by a solid construction. The body is made of steatite – a material with high thermal stability, and the knife contacts are covered with silver, which ensures excellent conductivity and minimizes the risk of corrosion. The KOMBI version, equipped with a dual tripping indicator (red eye on the ceramic body and a spring blade on the cover), facilitates quick identification of a blown fuse – both in the fuse base and in the disconnector. This makes diagnostics and replacement simple and intuitive.

It is worth noting the possibility of cooperation with the NVS 5 microswitch, which enables remote signaling of the fuse link operation. This is particularly useful in automatic monitoring and control systems for electrical installations.

Key features and benefits

• Protection against overload and short circuit: The NH3C gG 160A/500V fuse link effectively protects circuits against damage caused by excessive load or short circuit.
• Time-delay characteristic (gG): Allows for short-term exceeding of the rated current without disconnecting the circuit – ideal for applications with devices with high starting current (e.g. motors).
• Dual tripping indicator: Facilitates quick identification of a blown fuse, reducing installation downtime.
• Durable construction: Steatite body and silver-plated contacts ensure long-lasting and reliable operation even in harsh operating conditions.
• Compliance with standards: Meets the requirements of PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, which confirms its quality and safety.
• Rated breaking capacity: 120 kA at AC voltage provides effective protection even with high short-circuit currents.
• Wide range of rated voltages: Possibility of use in AC installations up to 500V and DC up to 250V increases the versatility of the product.

Choosing the NH3C gG 160A/500V fuse link is an investment in the safety and reliability of your electrical installation. It is a product worthy of trust for both professional installers and end-users looking for effective protection against the effects of short circuits and overloads.
