Summary

5. Miniature Circuit Breaker
Function of MCB
Protection against Overloads – a thermal delay (bi-metal) release initiates the disconnecting process and separates the contacts.
Protection against Short circuits - an electromagnetic instantaneous release (hammer- armature) performs the disconnecting process and separates the contacts.

6. Miniature Circuit Breaker
Tripping Characteristics
B – for line and cable protection in residential building installations (lighting and socket circuits)
C – for line and cable protection, particularly for electrical systems and equipment with higher making currents (groups of lamps)
D – for line and cable protection, particularly for electrical systems and equipment with very high making currents (welding transformers, motors)
