Future-proof solution for modern low-voltage switchgear
Schneider Electric is expanding wireless ZigBee communication in Smart Panels to set new standards for energy distribution.
5 Nov 2025Share
Schneider Electric, a leading provider of digital transformation for energy management and automation, presents a new generation of its Smart Panels with integrated, encrypted ZigBee-based communication. The wireless networking of energy distribution components is designed to enable a flexible, space-saving, and future-proof solution for modern low-voltage switchgear—especially in complex, partitioned switch cabinets according to IEC 61439 Form 3 and 4.
The new architecture is based on the Panel Server as a central gateway, which communicates via the IEEE 802.15.4 protocol with sensors and measuring devices such as PowerTag Energy, HeatTag, and now also MicroLogic Active, the trip unit of the MasterPacT MTZ open circuit breaker. In an extensive case study, Schneider Electric was able to demonstrate that wireless communication also works reliably in highly partitioned switch cabinets – with proper planning and antenna placement.
Wireless communication offers decisive advantages over traditional wired solutions. It reduces installation costs, saves space in the control cabinet, and allows for easy retrofitting – ideal for modernizing existing systems. The Panel Server Gateways are designed to communicate reliably with up to 128 participants and extend their range with external antennas.
Signal quality is ensured by measuring RSSI (Received Signal Strength Indicator) and PER (Packet Error Rate). The case study shows that stable communication is guaranteed when the recommended limits are observed – even with closed control cabinet doors and high levels of shielding.
The new Smart Panels are fully compatible with Schneider Electric's EcoStruxur architecture and support both local and cloud-based applications for energy management, maintenance, and documentation. With its wireless communication concept, Schneider Electric is deliberately focusing on intelligent and digital energy distribution in order to underline its role as a driver of innovation for sustainable and connected building technology with maximum safety.
