Fuse link - NH3C gTr 144A/400V/100kVA - transformer 004115402

NH3C gTr 144A/400V Fuse Link – Transformer Protection

This NH3C gTr 144A/400V fuse link, designed for transformer protection, is a key element ensuring the safety and reliability of the electrical installation. Designed to operate in alternating current (AC) circuits, it offers effective protection against the effects of short circuits and overloads, typical of transformer loads.

Characteristics and application

This fuse link is characterized by a rated current of 144A and is designed to operate at a voltage of 400V. Its utilization category, designated as gTr (according to IEC 60269 standard), precisely defines its application – protecting transformers from the effects of short circuits and overloads. This means that this fuse link has been specifically designed to respond quickly to failures in transformer power supply circuits, minimizing the risk of damage and downtime.

A combined (double) tripping indicator ensures both a quick response to sudden current surges and a delayed response to short-term overloads, which helps avoid unnecessary circuit disconnection. This ensures stable operation of the installation even under momentary loads, and in the event of a serious failure – it is effectively disconnected.

Mounting and compatibility

It is worth noting the lack of metal insulated grips (IMGL). This is important when selecting appropriate fuse holders, which must be compatible with this specification. A professional installer should take this aspect into account during the design and installation of the installation. Fuse links of this type are used in low-voltage switchgear, control cabinets and wherever reliable transformer protection is required.
