Miniature Circuit Breakers (MCBs) universal product selector



Miniature Circuit Breakers (also known as MCBs, and also sometimes modular DIN rail circuit breakers), are the most popular circuit breakers for residential, commercial and industrial applications with currents up to 63A (some breakers can offer higher values, but are less common). These circuit breakers offer reliable, maintenance-free electrical protection against short-circuits and overloads. In most parts of the world, those circuit breakers are installed on a 35mm DIN rail, and offer standardized 18mm modular width, making design and installation very intuitive.
They offer a wide range of short circuit protection levels (from 6kA to 25kA in general), as well as various tripping curves (B, C, D, K, Z, etc.) to adapt to specific loads.

Many global manufacturers offer those products: below, you can choose MCBs for your application, either by brand, or by technical characteristics, if you would like to compare brands for your project.
After choosing a brand or series, you will be able to fine-tune your selection criteria using our characteristic filter drop-down menus.
