A modular enclosure system designed to house electronics for controlling mechanical circuit breakers in electrical substations.

This enclosure system enabled Remsdaq to deliver a range of products to their customer base without the need to redevelop a new enclosure for each application, streamlining product development and supporting rapid deployment in the energy sector.

Remsdaq needed a robust, industrial-grade enclosure to support smart distribution network automation schemes. The design had to be modular, allowing for a mix-and-match approach to I/O expansion, and capable of housing advanced electronics for SCADA and automation requirements in demanding substation environments.

4D Products presented a range of innovative concepts, working closely with Remsdaq to refine the design into a modular system. The solution features a die-cast aluminium base unit with four configurable slots, which can be left blank, populated, or expanded with plug-in modules. Light pipe arrays were engineered so that LED indicators could be positioned flexibly across variants. CNC machined prototypes in production-intent materials were supplied for testing and refinement, ensuring the system was ready for production.

The first product to launch using this system was the Callisto nxl—a cost-effective, compact solution for small point count SCADA and automation. The modular enclosure supports a wide range of features, including multiple I/O options, Ethernet and serial ports, IEC 61850 compliance, integrated GPS (optional), and comprehensive diagnostic tools, all within a high-quality, industrial finish.
