What is a Miniature circuit breaker?
A Miniature Circuit Breakers is protection unit that trips and switch off the current on event of tow types of defaults:
– Overload : is a consumption of current that exceed the capacity of transporting cables, this tripping is achieved via a Bimetal system.
– Short circuit : a current flow btween Phase-Phase or Phase-Neural wire , this tripping is achieved via a magnetical coil.
Miniature circuit breaker are designed to protect cables and equipements
What is a Residual current Device?
This device reacts on earth leakage current, also throw a person Body. The residual current device trips on event of a current flow to the earth by values of 30mA, a Value that can cause an irreversible damage by human body.
The Residual current device is designed mainly to protect persons.
