Miniature Circuit Breakers (MCB)

Miniature circuit breakers (MCB) are electrical protection devices designed to protect circuits against overloads and short circuits. They automatically disconnect the power supply when the current exceeds the rated value, preventing damage to wiring, equipment and reducing fire risk. MCBs are essential components in residential, commercial and industrial electrical enclosures.

The category includes single-pole, double-pole, triple-pole and four-pole breakers in various current ratings and tripping characteristics (Type B, C and D). Standard DIN rail mounting allows quick and secure installation in modular enclosures. Clear labeling and compact design help optimize panel space.

Properly selected circuit breakers ensure reliable circuit protection, system stability and compliance with applicable electrical safety standards. Suitable for new installations and modernization projects.
