Fuse link - NH3C gTr 361A/400V/250kVA - transformer 004115406

Safety and reliability in transformer protection

NH3C gTr 361A/400V 250kVA fuse link is a key element in protecting electrical installations, primarily dedicated to protecting transformers from the effects of short circuits and overloads. The ETI Polam brand product, with catalog number 004115406, combines a solid construction and precise operation, ensuring long-lasting and effective protection.

This fuse link is characterized by a rated current of 361A and is designed to operate in circuits with a voltage of 400V. Its gTr utilization category, according to IEC 60269, indicates a special purpose for transformer protection – the gTr characteristic provides a delayed response to short-term current surges, typical for transformer starting, while simultaneously reacting quickly in the event of serious short circuits. This avoids unnecessary disconnection of the installation during normal operation, while effectively protecting against damage.

It is worth noting the presence of an operating indicator – combined (double), which facilitates the identification of a blown fuse and quick problem location. The lack of metal insulated clips (IMGL) indicates a standard design, suitable for most typical installations. This fuse link is indispensable wherever high reliability and effective transformer protection are required – from industrial facilities to power stations.

• Transformer protection: The special gTr characteristic ensures optimal protection against short circuits and overloads, minimizing the risk of damage and downtime.
• High breaking capacity: Short-circuit breaking capacity at 100kA guarantees effective disconnection of the circuit in the event of a failure.
• Operating indicator: Combined indicator facilitates quick identification of a blown fuse and fault location.
• Rated voltage: Designed to operate in 400V AC networks.
• Solid construction: Made of high-quality materials, ensuring durability and reliability.
• Compliance with standards: Meets the requirements of VDE 0636-21, confirming the safety and quality of the product.
