Whether in an industrial facility, sports venue or application in the field of renewable energy: Switchgear must operate reliably while also allowing cost-effective planning and assembly, as well as adaptation to changing requirements. This is precisely where Spelsberg’s GTi series comes in. The modular ISO switchgear system for applications up to 630 A combines robust industrial quality with a particularly assembly-friendly design.
A wide range of products for customized applications
With five flexibly combinable enclosure sizes featuring open side walls and continuous grid dimensions, individual enclosures can be easily combined to form larger distribution systems. The connection is made via an intelligent plug-in and connector system. “The enclosures are connected to one another without tools. It is therefore not necessary to knock out enclosure walls or fit additional seals,” explains Volker Bierbaum, product manager at Spelsberg for the GTi system. “This significantly accelerates assembly and facilitates modifications or extensions to existing systems.” Another advantage is the open side walls, which make wiring the switchgear easier. The wide range of flanges with different knockouts provides a suitable cable insertion for almost every application. The result is shorter assembly times and high flexibility for various applications. In addition to classic empty enclosures, the GTi series portfolio also includes, among other things, pre-assembled enclosures for circuit breakers, meters, sockets, busbars, fuses and switches. A wide range of accessory components is also available. This enables users to implement complete power distribution systems within one consistent system.
The system also meets the requirements of demanding environments in terms of robustness. The enclosures are made of robust polycarbonate and provide protection against dust, moisture and mechanical stresses. At the same time, they represent a corrosion-free alternative to conventional sheet-steel switch cabinets.
From planning to the finished switchgear
With its preconfigured enclosure solutions, the simple and flexible system gives users the opportunity to assemble ISO switchgear simply and quickly. Spelsberg also provides technical consulting. In addition, the expert in electrical installation and enclosure technology offers the option of implementing connection-ready switchgear from a single source. “The Business Unit Technical Solutions coordinates closely with the customer for this purpose, takes care of planning and manufacturing the switchgear, and hands it over to the customer after successful testing, including complete documentation,” emphasizes Volker Bierbaum.
With the GTi series, Spelsberg combines a wide range of products, technical expertise and practical services into a solution for modern switchgear construction. The intelligent assembly system reduces installation effort, simplifies project execution and creates scope for customized and fast solutions while maintaining a high level of quality and safety.
