Fuse link - NH4a gTr 909A/400V/630kVA - transformer 004116410

Transformer fuse link NH4a 909A

This NH4a fuse link with a rated current of 909A is designed to protect transformers from the effects of short circuits and overloads. Designed to operate in circuits with a voltage of 400V and a power of up to 630kVA, it is a reliable safety element for electrical installations. Its construction, compliant with IEC 60269, ensures effective protection and long-term operation.

Solid protection for your installation

The fuse link from ETI POLAM guarantees safety and stable operation in demanding applications. Its gTr characteristic makes it ideal for protecting transformers, which are particularly susceptible to sudden current surges during start-up or in the event of a failure. The top indicator allows for quick visual identification of a blown fuse, making it easier to locate and repair faults.

• Rated current 909A: Provides adequate protection for circuits with high loads.
• Rated voltage 400V: Adapted to standard mains voltages.
• Utilization category gTr: Specifically designed for transformer protection.
• Top indicator: Enables quick and easy identification of a blown fuse.
• Size NH4a: Standard fuse size, ensuring compatibility with most installations.

Installation and application

The NH4a fuse link is used in electrical switchgear, transformer stations and other installations requiring reliable protection against overloads and short circuits. Installation is simple and intuitive, and the solid construction guarantees long-lasting and trouble-free operation. The lack of metal insulated grips (IMGL) simplifies installation in some types of fuse boxes. It is a key component for ensuring continuity of power supply and safety of electrical equipment.
