ABB Miniature Circuit Breakers (MCBs) deliver robust protection against overloads and short circuits across residential, commercial, and industrial environments. Available in configurations from 1-pole to 4-pole, with trip characteristics tailored for diverse loads, and backed by a modular design ethos that supports sustainability and accessory integration—they are a trusted solution for modern electrical safety and efficiency.
Description
ABB’s MCBs are compact, modular circuit protection devices designed to safely interrupt overloads and short circuits in low-voltage systems. Integrating thermal-magnetic tripping mechanisms, these breakers rapidly disconnect circuits during fault conditions, safeguarding wiring and reducing fire risks.
