Fuse link - NH000 gG 40A/400V - time-lag 004181110

Reliable installation protection with NH000 fuse link

The NH000 gG 40A/400V fuse link is an element used to protect electrical installations from the effects of overloads and short circuits. It is a proven component that meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. The fuse link is characterized by a time-delay characteristic, which means that it allows for short-term exceeding of the rated current without disconnecting the circuit – an ideal solution for devices with motors or other loads with high starting current.

Design and application

The NH000 knife fuse link is made of high-quality materials, which guarantees its reliability and durability. The steatite body provides thermal stability, and the silver-plated brass knife contacts minimize resistance and ensure a secure connection. The fuse link has a dual tripping indicator – a red eye in the central part of the ceramic body and a spring-loaded plate on the top cover – which makes it easy to quickly identify a blown fuse. This allows both the installer and the end user to easily check the condition of the fuse link. The ability to cooperate with the NVS 5 microswitch enables remote signaling of tripping, which is particularly useful in monitoring and automation systems.

Advantages and benefits

• Protection against overloads and short circuits: Provides effective protection of the electrical installation against damage caused by malfunctioning circuits.
• Time-delay characteristic (gG): Allows for short-term exceeding of the rated current without disconnecting the circuit, which is important for devices with motors or other loads with high starting current.
• Dual tripping indicator: Facilitates quick identification of a blown fuse, both visually and remotely (using a microswitch).
• High quality workmanship: Steatite body and silver-plated knife contacts guarantee reliability and durability.
• Compliance with standards: Meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, which confirms its safety and effectiveness.
• Short-circuit breaking capacity: 120 kA – a high value ensures safety even in the event of serious short circuits.
• Power losses: Low power losses of 3.4 W minimize the impact on the energy efficiency of the installation.

It is important to remember to select the correct fuse link for a specific application, taking into account the rated current, rated voltage and operating characteristics of the circuit.
