Fuse link - NH2 gTr 72A/400V/50kVA - transformer 004114400

NH Fuse Links – Reliable Installation Protection

The NH2 72A gTr 400V/50kVA fuse link is a protective element designed to protect electrical circuits, especially transformers, from the effects of overloads and short circuits. Its construction and gTr characteristic ensure a quick and effective response in the event of a failure, minimizing the risk of damage and downtime. This is a key component in power distribution systems, guaranteeing safety and continuity of supply.

Characteristics and application

This fuse link is characterized by a rated current of 72A and is adapted to work in circuits with a voltage of 400V. The gTr designation indicates its specialization – protecting transformers from the effects of short circuits and overloads. Therefore, in the event of a transformer failure, the fuse link quickly blows, disconnecting it from the network and preventing further damage. It has a combined (double) tripping indicator, which facilitates the identification of a blown fuse without the need for disassembly.

Construction and mounting

The NH2 fuse link is made of high-quality materials, which ensures its durability and reliability. Mounting is done in dedicated NH2 fuse holders, which provide a stable electrical connection. The lack of metal insulated grips (IMGL) indicates a standard construction, compatible with most fuse holders available on the market. Replacing a blown fuse is simple and intuitive – just disconnect the power, remove the old fuse and insert a new one.
