Fuse link - NH1C gG 63A/690V - time-lag 004184312

Reliable installation protection with NH fuse links

Blade fuse links, also known as NH fuse links, are a key element in protecting electrical installations from the effects of short circuits and overloads. The NH1C gG 63A/690V fuse link offered provides effective and proven protection, meeting the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. It is an essential component for both professional installers and end users, guaranteeing the safety and continuity of electrical systems.

Characteristics and application

The NH1C gG 63A/690V fuse link is a device designed to protect wires and circuits with a time-delay characteristic (gG). This means that it allows for short-term exceeding of the rated current without disconnecting, which is particularly important when starting devices with motors or other pulse loads. The rated current of this fuse link is 63A at AC 690V and DC 250V. The short-circuit breaking capacity AC reaches as much as 100kA, which proves its high effectiveness in emergency situations.

Construction and distinguishing features

The fuse link is made of high-quality materials – a steatite body (thermally stable material), silver-plated brass knife contacts and aluminum covers providing corrosion resistance. The inside of the fuse link is filled with quartz sand of a special granulation, which guarantees stable electrical parameters and high breaking capacity. It is equipped with a double operating indicator – a red eye on the ceramic body and a springy plate on the top cover – which facilitates quick identification of a blown fuse link. Additionally, the indicator on the top cover enables cooperation with the NVS 5 microswitch for remote signaling of operation.

• Strength and durability: The steatite body provides resistance to high temperatures and mechanical damage.
• Effective protection: Short-circuit breaking capacity of 100kA guarantees quick disconnection of the circuit in case of failure.
• Ease of use: Double operating indicator facilitates identification of a blown fuse link, and the possibility of remote signaling increases system safety.
• Versatility: Suitable for protecting various electrical circuits with a time-delay characteristic (gG).
• Safety: Made of silver-plated brass ensures good electrical contact and minimizes the risk of overheating.
