Resistor block BK12M U2 IRAK 434.331.003-49 CEM Resistor 00-00008838

Crane resistor blocks type BK12M IRAK 434.331.003-49 are used for starting and speed regulation of crane electric motors of direct and alternating current. Resistor block BK12M IRAK 434.331.003-49 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.
