domeashop Molded case circuit breaker

Discover our selection of molded-case circuit breakers designed to provide electrical protection for industrial installations. Installed in a panel or cabinet, they protect circuits against overloads and short circuits, with ratings and breaking capacities suited for commercial and industrial electrical systems. Their use is recommended when modular circuit breakers are no longer sufficient: high-current feeders, power supplies to subpanels, machines, motors, or equipment requiring precise adjustment, selectivity, and reliable tripping. The Legrand, Schneider Electric, Eaton, and Hager product lines offer 3-pole or 4-pole solutions depending on the installation's architecture.

It protects a low-voltage circuit against overloads and short circuits, particularly in commercial and industrial distribution panels.

Molded-case circuit breakers are generally designed for higher currents, greater breaking capacity, and more advanced settings.

A 3P model protects all three phases; a 4P model adds neutral disconnection, which is useful depending on the grounding configuration and the installation.

Not always. Differential protection requires a compatible differential block or a device that incorporates this function.

You must check the rating, the number of poles, the breaking capacity, the type of trip mechanism, the available settings, and compatibility with the control panel.
