Meba mcb MB8 type can protect and control of circuit against overload and short circuit, in building installation-such as houses, offices, commercial complex, motor system(D curve) and industrial installation-for switching, control, protection and regulation of electrical circuits. Also in switch-gear panels, railway and marine application.Applicable to terminal and pin/fork type busbar connection,Protection against both overload and short circuit High short-circuit capacity
Feature:
MAGNETIC COIL: ensures the switching of short-circuit, speaking within the following ranges: 5 to 10 times rated current (Type C), 3 to 5 times rated current ( Type B ), 10 to 20 times rated current ( Type D )
BIMETAL: ensures the breaker trip when overloaded.
ARC CHAMBER: effectively dissipates the electric arc that is generated by the opening contacts of the trigger mechanism in the presence of an overload or short circuit.
