Miniature Circuit Breakers

Code: 000096
Description: MCB & RCCB

Meta MEC series modular circuit breakers
- Designed to fit into single and three phase distribution boards for outgoing circuit protection
Complete range of modular devices designed to offer property or personnel protection from earth leakage fault.

Miniature Circuit Breakers
It is placed directly upstream of the loads and is designed to protect final loads.
It is ideal for the protection of circuits in industry and building, house sector and ensures the following functions: protection against short-circuit and overload currents, isolation , protection of persons against indirect contact.

Residual Current Devices
Residual current devices provide the functions of isolation, switching and earth leakage protection of electrical circuits. They have a residual current operated electro-mechanical release which operates without any auxiliary source of supply to open a circuit automatically in the case of an earth leakage fault between phase and earth greater than or equal to a threshold of 15, 30, 100, or 300mA.
