Resistor block BK12M U2 IRAK 434.331.003-26 Resistor CEM PK000001417

Crane resistor blocks type BK12M IRAK 434.331.003-26 are used for starting and regulating the speed of crane electric motors of direct and alternating current. The BK12M IRAK 434.331.003-26 resistor block is an open-type design consisting of two steel side plates connected by two bars with a transverse tie. Resistors are mounted on the side plates and the transverse tie on tubular porcelain insulators.
