Resistor block BK12M U2 IRAK 434.331.003-03 Resistor CEM PK000001363

Crane resistor blocks type BK12M IRAK 434.331.003-03 are used for starting and regulating the speed of crane electric motors of direct and alternating current. Resistor block BK12M IRAK 434.331.003-03 is an open-type design consisting of two steel side plates connected by two bars with a transverse tie. Resistors are installed on the side plates and the transverse tie on tubular porcelain insulators.
