DGG 12kV Outdoor Dropout Fuse Cutout – RW12/HRW12 Series for Distribution Networks

The DGG (H)RW12-12(F) series is a 12kV outdoor AC dropout fuse cutout designed for overhead distribution networks and transformer primary-side protection.

The series includes ceramic-insulated and polymer-insulated versions, with standard and loadbreak configurations available according to the specified model.

Its replaceable fuse-link arrangement allows the fuse cutout to provide overcurrent protection while maintaining a practical mechanical structure for utility distribution applications.

The appropriate version should be selected based on system voltage, current rating, required interrupting capacity, insulation conditions and switching requirements.

Product Description

12kV Fuse Cutout Solutions for Distribution Network Protection

The (H)RW12-12(F) series is developed for medium-voltage distribution applications where a practical combination of overcurrent protection, fuse-link replacement and outdoor installation is required.

This product family is intended for use in distribution systems with a 12kV equipment voltage class, including suitable 10kV nominal distribution networks.

A major consideration when selecting this series is the choice between insulation and operating configurations. Ceramic-insulated and polymer-insulated versions are available within the model family, allowing project designers to select equipment according to mechanical, environmental and electrical requirements.

The conventional dropout configuration relies on the fuse link for overcurrent protection. When the fuse element operates under fault conditions, the fuse holder is released and moves into a visible open position.

For projects requiring controlled load switching, the corresponding F-type configuration should be considered. The exact loadbreaking capability must be verified using the technical documentation for the selected model.

The series is suitable for power utilities, distribution network contractors and electrical equipment buyers who need a defined 12kV fuse cutout solution rather than a general-purpose fuse product.

Model Variations

Model	Insulation	Configuration
RW12-12	Ceramic	Standard dropout
HRW12-12	Polymer	Standard dropout
RW12-12F	Ceramic	Loadbreak version
HRW12-12F	Polymer	Loadbreak version

The model designation identifies the insulation and operating configuration within the product family. The exact dimensions, electrical ratings and available accessories should be checked against the corresponding model datasheet.

Key Features

1. Defined 12kV Product Series

Designed around a 12kV equipment voltage class for compatible medium-voltage distribution applications.

2. Insulation Options

Ceramic and polymer housing versions are available within the product family to accommodate different project specifications.

3. Standard and Loadbreak Versions

Different operating configurations allow buyers to specify whether a conventional dropout fuse or a model with rated loadbreaking capability is required.

4. Replaceable Fuse-Link Arrangement

Compatible fuse links can be selected according to the protection scheme and replaced after operation and equipment inspection.

5. Visible Fuse Operation

The dropout mechanism provides a visible indication of fuse operation, supporting field inspection and fault identification.

6. Application-Oriented Selection

Electrical and mechanical configurations can be evaluated against transformer capacity, available fault current, installation environment and protection coordination requirements.
