Fuse link - NH4a gTr 144A/400V/100kVA - transformer 004116402

NH4a gTr 144A/400V Fuse Link – Transformer Protection

This NH4a 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.

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, indicates specialization in transformer protection. This means that this fuse link has been designed to withstand short-term current surges during transformer start-up, while also providing a quick response in the event of more serious failures. This minimizes the risk of transformer damage and ensures continuity of supply.

Construction and additional information

The upper indicator allows for visual control of the fuse link status – whether it has operated and needs to be replaced. The absence of metal insulated grips (IMGL) indicates a standard construction, compatible with most available fuse holders. It is worth remembering that proper selection of the fuse link is crucial to ensure optimal protection of the installation. The selection should take into account the transformer power (100kVA) and the specifics of the load.

By choosing this fuse link, you are investing in the safety and long-term operation of your electrical installation. This is particularly important in industrial and energy applications where power supply reliability is critical.
