MINIATURE CIRCUIT BREAKER

MINIATURE CIRCUIT BREAKERS

MINIATURE CIRCUIT BREAKER is an efficient current limiting device, well designed and engineered to provide protection against overload and short circuit through two different tripping devices operating on a trip-free switching mechanism to delayed thermal trip for protection against overload and quick acting electromagnetic trip for protection against short circuits.

MINIATURE CIRCUIT BREAKER can be used with reliability for providing protection of both lighting as well as motor circuits.

The CONTACT SYSTEM bears testimony to the latest advances made in technological developments. By using solid silver contact metal, it has been possible to achieve outstanding values of low cantact resistance and low internal power loss.

The SWITCHING MECHANISM operates without vibration and prevents contacts welding. All moving pieces are embedded in fire retardant material resulting in an extraordinary service life and a high corrosion resistance.
