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.

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)

Miniature Circuit BreakerSummary of Features

• Installation and removal of MCB without removing the bus bar

• 80 mm device height – compatible with DIN rail products

• Twin-purpose terminal (lift/open mouthed) with guide for secure connection

• both releases work independent of each other.

• Wide range of accessories, most items in snap-on design

• Internal tripping is independent of the toggle position , guarantees proper tripping even in case the operating toggle is blocked or held by the operator
