Fuse link - NH00 gG 100A/690V - time-lag 004182314

Reliable installation protection with NH00 fuse link

NH00 gG 100A/690V fuse link is an element ensuring effective protection of electrical installations against the effects of overloads and short circuits. Designed for both industrial applications and public buildings, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its construction and electrical parameters guarantee reliable operation in demanding conditions.

Characteristics and application

NH00 blade fuse with gG (time-delay) characteristic is a universal solution for protecting cables and devices. The gG characteristic means that the fuse allows for short-term exceeding of the rated current, which is particularly important when starting devices with electric motors or other loads with high inrush current. The rated current of 100A at 690V AC makes it suitable for protecting circuits with medium power. In addition, the fuse has a rated DC voltage of 250V, expanding its range of applications.

Construction and functionality

The NH00 fuse has been designed with durability and reliability in mind. The steatite body provides thermal stability, and the silver-plated knife contacts guarantee low transition resistance and minimize the risk of overheating. The fuse is equipped with a double tripping indicator – a red eye in the central part of the ceramic body and a springy plate on the top cover – which facilitates quick identification of a blown fuse. This allows both installers and end-users to easily check the condition of the fuse without the need for disassembly. Additionally, the ability to cooperate with the NVS 5 micro-switch enables remote signaling of tripping, which increases safety and monitoring efficiency. The value of the short-circuit interrupting capacity AC is 100kA, which demonstrates high effectiveness in protecting against the effects of short circuits.
