Fuse link - NH2 gG 280A/500V - time-lag 004185220

Reliable installation protection with NH2 gG 280A/500V fuse link

This knife-type fuse link, catalog number 004185220, is a key element in protecting electrical installations from the effects of overloads and short circuits. Designed for industrial applications, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its solid construction and electrical parameters guarantee reliable operation in demanding conditions.

Characteristics and application

The NH2 gG 280A/500V fuse link is characterized by a rated current of 280A and a rated voltage of 500V AC. The "gG" designation indicates its versatility – it is suitable for protecting cables against overloads and short circuits. This makes it a versatile choice for both installers and end-users. The rated short-circuit breaking capacity is as high as 120kA, ensuring effective protection even in the event of serious failures.

Construction and functionality

The fuse link has been designed with durability and ease of use in mind. The body is made of durable steatite, and the knife contacts are silver-plated – this ensures thermal stability and minimizes the risk of corrosion. Particular attention has been paid to the operation indicator. The "KOMBI" version is equipped with a double indicator – a red eye on the ceramic body and a spring-loaded plate on the top cover. This solution provides very good visibility of the fuse link's operating status, both in fuse bases and disconnectors. Additionally, the upper indicator allows cooperation with the NVS 5 microswitch for remote signaling of operation.
