Resistor block BK12M U2 IRAK 434.331.003-48 CEM Resistor 00-00008837

Crane resistor blocks type BK12M IRAK 434.331.003-48 are used for starting and regulating the speed of crane electric motors of direct and alternating current. The BK12M IRAK 434.331.003-48 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. Series: BK12M Design document number: IRAK 434.331.003 Scheme number: 48 Number of terminal clamps: 8 Protection degree: IP00 Material: fe-cr-al Step designations: P10-P11, P12-P13: 66.6-81.4 Ohm P11-P14, P13-P16: 10.8-13.2 Ohm P14-P15, P16-P17: 259.2-316.8 Ohm
