Fuse link - NH2 gTr 144A/400V/100kVA - transformer 004114402

NH Fuse Links – Reliable Installation Protection

NH2 144A gTr 400V/100kVA fuse link is a protective element designed to protect transformers from the effects of short circuits and overloads. Its construction and gTr characteristic ensure a quick and effective response in the event of a failure, minimizing the risk of damage and downtime in the system. It is a key component in electrical installations where high reliability and safety are required.

Characteristics and application

This fuse link, with a rated current of 144A and a voltage of 400V, is primarily used in power supply circuits for transformers. The gTr (transformer) characteristic means that this fuse link reacts more slowly to short current surges, which is important when starting devices with motors or transformers – this avoids unnecessary tripping of the circuit during normal operation. It has a combined (double) tripping indicator, which facilitates the identification of a blown fuse.

Construction and mounting

NH2 fuse links are characterized by a solid construction, ensuring high resistance to environmental conditions and mechanical damage. Mounting is done in dedicated NH2 fuse holders, which guarantees a stable connection and safe operation. The lack of metal insulated grips (IMGL) means a standard construction, compatible with most fuse holders available on the market. It is important to select the correct holder for a specific application and to follow appropriate safety procedures when replacing the fuse link.
