For decades, electrical rooms have operated on proven, reliable electrical architectures. But as Electricity 4.0 reshapes how power is generated, distributed, and consumed, these infrastructures are now more critical and capacity-strained.
Facilities need deeper visibility, smarter energy use, and stronger safety measures, delivered through digital solutions simple enough for non-digital experts to use with confidence. At the same time, electrical distribution is shifting toward integrated, low-effort systems that support a more sustainable future, reduce emissions, and help organizations consume electricity more intelligently.
Global energy demand is projected to grow nearly 4% annually through 2027, yet much of today’s equipment was built long before digitalization became essential, creating a gap between modern expectations and the realities of existing infrastructure. Rather than discard these reliable architectures, modernization can elevate them by building an intelligent digital layer on top of a proven mechanical foundation to provide:
- Deeper visibility and insights
- Tighter safety controls
- Reduced energy use
A new generation of digital-ready air circuit breakers, sensors, and electrical panel architectures makes this possible. This shift aligns with evolving International Electric Code (IEC), Underwriters Laboratories (UL), and National Fire Protection Association (NFPA) standards that increasingly view digitalization as fundamental to proactive protection and lifecycle optimization.
Three pillars of circuit breaker innovation
Three strategic pillars are driving this transition: simplifying digital adoption, modernizing existing assets, and aligning with the next wave of digital-focused standards.
1. Simplicity is becoming a safety boundary
For panel builders and design firms, simplicity is important. Devices must commission easily, integrate cleanly, and avoid adding complexity to the assembly process. When systems are harder to install or configure, risk increases; complexity can compromise both performance and safety.
This is why simplicity is becoming a design-level safety requirement. Digital capabilities must be intuitive, low-effort, and reliable without specialized knowledge. True innovative digital functions are seamless and don’t add complexity, such enablers include:
- Wireless connectivity (e.g., Zigbee) that removes wiring complexity, eases commissioning, and pairs seamlessly with IoT gateways, becoming the entry point to digitalization.
- Unified data models that keep information consistent from device to panel to software.
- Simple, cyber-aware communication pathways that don’t burden installers.
- Architectures designed for right-first-time setup, reducing costly debugging.
- New digital safety functions—such as Energy Reduction Maintenance Setting (ERMS) activation—allow maintenance teams to reduce arc-flash risk more quickly.
2. Modernization elevates what already works
This is where the real transformation is happening, much as the automotive world underwent years ago. Cars once relied on isolated mechanical systems and standalone sensors; today, those components are unified under a central digital brain that delivers greater insight, efficiency, and safety.
Electrical panels are undergoing the same transformation. Even at 10–15 years old, they remain mechanically excellent and far from end-of-life. They don’t need replacement; they need intelligent augmentation. By adding digital layers, these proven mechanical assets become a part of a smarter, integrated ecosystem. This type of modernization:
- Adds digital sensing to proven mechanical platforms instead of replacing them.
- Brings wireless connectivity to brownfield installations not designed for digital infrastructure.
- Supports circularity by extending asset life and reducing material consumption.
- Unlocks analytics, condition monitoring, and predictive maintenance even in pre-digital systems.
This shifts modernization efforts from a costly overhaul to a low-disruption improvement that maximizes the value of what’s already effective.
3. Standards are shifting from passive compliance to proactive safety
IEC, UL, and NFPA organizations define a modern electrical panel as both mechanically safe and digitally capable.
- IEC 61439 and digital technical specifications
Recent evolutions now recognize digital devices inside assemblies, including wireless communication, cybersecurity expectations (aligned with IEC 62443), interoperability requirements, and guidance on auto-discovery and standardized data models. These changes directly affect panel builders, who ensure assemblies remain compliant as digital devices become the norm. - 2026 protection and safety updates
Upcoming changes will require customers to specify their level of safety, with digital insight acting as a mechanism for enhanced protection.
- Condition-based maintenance (NFPA 70E, IEC TR 63482)
Time-based maintenance is giving way to:- Adaptive maintenance informed by real data
- Extended intervals when the equipment shows healthy behavior
- Earlier intervention when sensors detect risk

It introduces a new level of digital capability that combines protection with modern sensing, connectivity, and serviceability through the MicroLogic Active trip unit.
For panel builders and design firms, the MasterPacT MTZ Active offers a clear pathway to deliver digital-ready panels without altering proven mechanical designs. Its value is anchored in two major advancements: wireless simplicity through Zigbee and safer operation through one-button ERMS:
- Richer electrical insights through enhanced measurement and monitoring
- Integrated Zigbee wireless connectivity for simplified design, flexible installation, and reduced wiring complexity when pairing with the Panel Server
- Advanced safety via one-button ERMS activation, providing immediate arc-flash hazard reduction during maintenance
- Faster commissioning with an intuitive, low-effort setup suitable for non-digital experts
- Stronger serviceability through logs, diagnostics, and alarms directly accessible from the device
- Cloud-ready for real-time data access
- Cyber-aware communication that supports secure data flows from device to panel to software
- Sustainability benefits through replaceable electronics and extended device life
With these capabilities, facilities can retain the mechanical systems that still perform reliably while adding the digital intelligence needed for modern, interconnected environments. It positions customers to meet emerging requirements while unlocking new operational value.
Modernize by augmenting what works
