Resistor block BK12M U2 IRAK 434.331.003-42 CEM Resistor 00-00003370

Crane resistor blocks type BK12M IRAK 434.331.003-42 are used for starting and regulating the speed of crane electric motors of direct and alternating current. Resistor block BK12M IRAK 434.331.003-42 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.
