Enclosed MCCB & RCD Units

Our Enclosed MCCB & RCD Units provide high-current circuit protection for commercial, industrial and three-phase electrical installations. The range includes standalone enclosed moulded case circuit breakers as well as enclosed CBR units combining MCCB and residual current protection within a single assembly.

Enclosed MCCB Protection

Enclosed MCCBs provide overload and short-circuit protection for higher-current electrical systems while keeping the breaker securely housed inside a dedicated metal enclosure. Four-pole configurations make them suitable for three-phase and neutral applications where reliable isolation and circuit protection are required.

Enclosed MCCB + RCD CBR Units

CBR models combine moulded case circuit breaker protection with residual current protection, reducing the need for separate protective devices. Depending on the model, adjustable protection settings allow the unit to be configured to suit the requirements of the installation.

Designed for Commercial and Industrial Installations

These enclosed protection units are suitable for applications such as distribution systems, machinery supplies, commercial installations and industrial electrical systems where higher current ratings and robust circuit protection are required.

Choose the Correct Enclosed MCCB or CBR

Select the appropriate unit according to the required current rating, number of poles, breaking capacity and whether residual current protection is required. Always check the individual product specification before installation.
