Thermomagnetic overcurrent circuit breakers are critical electrical protection devices that combine thermal and magnetic tripping mechanisms to safeguard circuits from overloads and short circuits. These devices automatically interrupt current flow when it exceeds safe levels, utilizing a bimetallic strip for thermal protection (responding to sustained overloads) and an electromagnetic coil for instantaneous response to short circuits. Major product types include plug-in, stationary, and draw-out configurations, with applications spanning industrial, commercial, and other sectors.

The market growth is driven by increasing electrification across industries, stringent safety regulations, and modernization of power infrastructure. The industrial segment dominated with 42% market share in 2024, fueled by demand from manufacturing and energy sectors. Recent technological advancements include smart circuit breakers with IoT capabilities for remote monitoring, though cost sensitivity in developing markets remains a challenge. Leading manufacturers like Eaton, ABB, and Siemens continue to expand their product portfolios through innovation and strategic partnerships to capitalize on the growing demand for reliable circuit protection solutions.
