Product Description:
The RKL4301 motor cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is a factory-terminated power lead that links an IndraDrive inverter to its corresponding servo or induction motor, carrying three-phase supply lines and protective earth while maintaining defined shielding. By offering a pre-tested assembly, it eliminates field crimping and shortens installation time inside dynamic automation axes and handling modules.
The cable is rated for 5,000,000 flexing cycles in continuous-motion drag-chain layouts, meaning it withstands repeated bending without conductor fatigue. During motion, the conductor bundle may be curved down to a dynamic minimum of 7.5xD, where D represents the outer diameter, while stationary installations can use a tighter static value of 5xD. Functional temperature limits span from -30 °C for cold-start operation up to 80 °C during sustained load, so the jacket material remains pliable in refrigerated halls and stable near warm drive enclosures. These parameters together define the permissible mechanical stress window and thermal envelope that the cable can endure when routed through energy chains, torsion arms, or linear slides.
This ready-made assembly is identified as the Basic model and classified by Bosch Rexroth as a Power Cable, confirming that only the motor’s mains conductors are carried inside the sheath. Factory ends are fitted with a keyed Plug Connector RLS1101 on the drive side and a compact Plug Connector RLS0721 on the motor side, enabling tool-less locking and correct shield termination. The plug set supports quick exchange during maintenance and maintains the cable’s EMC performance. Because the jacket compounds withstand abrasion and oils, the cable can be installed in floor-level chains or overhead carriers without extra conduit. Storage temperature limits mirror the operational range, so no special packaging is required between assembly and commissioning.
