Pluggable electrical installations are the ideal solution for projects that require speed, flexibility, and reliability. These systems comply with all relevant standards, including NEN 1010, IEC 61535, and NEN 8012, providing a standardized approach that reduces installation errors, lowers costs, and significantly shortens installation time. But which connector series is the right choice for your project: GST^® or RST^®? This guide has been developed to help you make the right decision.

GST^® or RST^®: which series fits your project?
The first step in selecting the right connector series is to consider the environment in which the installation will be used. GST^® is designed for dry indoor environments such as offices, commercial buildings, and prefabricated installations. It is an excellent choice for both lighting and power distribution circuits.

RST^®, on the other hand, is specifically engineered for demanding environments, including humid, dusty, and industrial applications. Available in MICRO, MINI, CLASSIC, and POWER variants, the RST^® series offers solutions for outdoor installations, greenhouses, and heavy-duty power distribution. With IP66, IP68, and IP69 protection ratings, as well as ATEX-certified versions, RST^® delivers reliable performance even under the most challenging conditions.

Technical specifications and applications
Technical requirements play an important role in selecting the right connector series. For indoor applications up to 16 amps, GST15^® is the ideal solution, while GST18^® supports currents up to 20 amps.

For outdoor installations and higher power demands, the RST^® portfolio offers several options, ranging from the compact RST16^® for smaller applications to the RST50^® for heavy-duty power circuits up to 50 amps.

Environmental factors such as moisture, dust, and chemical exposure should also be taken into account. While GST^® offers IP20/IP40 protection for dry indoor environments, RST^® provides protection ratings up to IP69, making it suitable for harsh operating conditions.

Safety and correct installation
Safety is a key consideration in every installation. All connections must be installed in a de-energized state and equipped with the appropriate locking mechanism and strain relief. The use of original Wieland components is essential to ensure compliance with applicable standards and to guarantee a safe and reliable installation.

Proper installation also requires well-trained installers who carefully verify cable specifications, including cable diameter and stripping length. After installation, the system should be tested thoroughly, with all labeling and documentation completed according to the as-built situation.

Practical selection tables and checklists
The concise guide includes a clear selection table covering all relevant criteria, including current rating, number of poles, fire classification, and mechanical load. This enables installers and specifiers to quickly determine which connector series best matches the requirements of their project.

In addition, the guide provides practical checklists for preparation, installation, and commissioning, along with links to datasheets and installation instructions.
