Product information

Description

The Eti-Polam NH3 fuse link is a specialized electrical protection device engineered specifically for the reliable safeguarding of distribution transformers. With a rated current of 144A and a gTr characteristic, this component is optimized for 100kVA transformers operating at 400V. As a WT-3 size fuse, it provides robust performance in industrial power distribution networks, ensuring that circuits are interrupted effectively during overloads or short-circuit events to prevent equipment damage.

Advantages

This fuse link offers high operational reliability and precision in its protection characteristics, specifically tailored for transformer applications. The gTr class ensures that the fuse can withstand the specific inrush currents associated with transformer operation while providing rapid disconnection during fault conditions. Its durable construction and standardized WT-3 dimensions allow for seamless integration into existing fuse bases and electrical distribution panels, maintaining high safety standards in demanding industrial environments.

Suitable for

  • Protection of 100kVA distribution transformers
  • Industrial power distribution systems
  • Electrical networks operating at 400V
  • Applications requiring gTr characteristic protection

When it may not be suitable

This fuse is not intended for general-purpose circuit protection where a gG characteristic is required, as its performance is specifically tuned for transformer loads. It should not be used in systems exceeding the 400V voltage rating or in applications where the transformer capacity significantly deviates from the 100kVA specification.

Key specifications

  • Rated current: 144A
  • Rated voltage: 400V
  • Transformer capacity: 100kVA
  • Fuse size: WT-3
  • Characteristic: gTr

How to use

The fuse link should be installed by a qualified electrician into a compatible WT-3 size fuse base. Ensure that the power supply is disconnected before insertion or replacement. Align the fuse correctly within the base contacts and use an appropriate fuse handle or extraction tool to ensure secure seating. Once installed, verify that the visual indicator is intact and the connection is tight before restoring power to the system.

What to consider before purchase

  • Verify the transformer power rating matches the 100kVA specification
  • Ensure the fuse base is compatible with the WT-3 size
  • Confirm that the system voltage is 400V
  • Check that the gTr characteristic is appropriate for the specific protection requirements of your installation

Usage recommendations

Always use appropriate personal protective equipment when handling electrical components and ensure the circuit is de-energized before performing any maintenance or replacement of the fuse link.
