Shelly Group SE is expanding its Pro product portfolio and showcased its new "Smart Miniature Circuit Breaker" (MCB) product line at the Internationale Funkausstellung (IFA) in Berlin. With this innovation, Shelly Group is accelerating its entry into the professional building and energy management market while reinforcing its position as a technology leader. With the introduction of Smart Miniature Circuit Breakers, Shelly Group is making a significant leap into the professional building and energy Management market by combining maximum electrical safety with advanced smart control.
The real-time monitoring capabilities allow early detection of anomalies in energy consumption - such as unusual usage patterns, overconsumption, or malfunctions in connected appliances - enhancing overall building safety. In critical events like fire or flooding, the system enables remote power disconnection per branch, minimizing risk and damage. Shelly Smart MCBs offer a highly efficient, space-saving and cost-effective solution that elevate both safety and energy intelligence in modern buildings.
The new Shelly Smart Miniature Circuit Breakers (MCBs) are the world's first smart MCBs in a compact 1M form factor. They are available with B- and C-trip characteristics, 1P+N poles, and rated currents of 6A, 10A, 13A, 16A, 20A, and 25A. For communication, two modern options are available: Z-Wave LR and Bluetooth combined with Zigbee.
These devices offer a high level of safety alongside broad connectivity, unlocking a wide range of applications in professional electrical installations and building automation. In addition to the newly introduced MCBs, Shelly is further expanding its portfolio with a comprehensive line of professional smart circuit breakers. With the launch of the new Shelly Pro Smart Circuit Breaker product line, the company introduces models ranging from 1- to 4-pole devices supporting currents of 10A, 16A, 25A, 32A, 40A, and 63A.
The devices are available in compact DIN-rail form factors (2M for 1-pole, 3M for 2-pole, 4M for 3-pole, and 5M for 4-pole versions) and are designed for standard residential and industrial applications at 230 V AC (1- and 2-pole) and 400 V AC (3- and 4-pole). All breakers feature integrated Ethernet, Wi-Fi, and Bluetooth connectivity, ensuring maximum flexibility, seamless integration, and reliable performance across a wide variety of use cases. According to market research firm Market Research Intellect, the global smart circuit breaker market is estimated at approximately USD 2.5 billion in 2024 and is expected to grow at a compound annual growth rate (CAGR) of about 10.5% to exceed USD 5.8 billion by 2033.
Key drivers of this growth include rising demand for energy efficiency and safety, the increasing integration of smart grids and renewable energy, as well as the broader adoption of smart homes, intelligent buildings, and industrial solutions. Additional factors include technological advancements in the Internet of Things, artificial intelligence, and cloud integration, along with stricter regulatory requirements for energy savings and electrical safety. The development of Shelly Smart Miniature circuit Breakers has been completed.
Certification by DEKRA will begin at the end of September and is expected to take approximately two months, followed by certification from VDE. Mass production is scheduled to begin immediately after certification is completed. Market launch is planned for early 2026.
