Product Description:
The RKL4554 is a motor power cable manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It carries three-phase power and control conductors from drive controllers to IndraDyn and other servo motors, providing a pre-qualified link in industrial automation cells. The cable’s mechanical robustness also suits continuous flex energy-chain routes.
The outer diameter measures 17.0 mm, a size that balances current-carrying capacity with routing space inside cable trays. Its mutual capacitance of 0.8 nF/m keeps reactive current low, allowing drives to maintain accurate torque regulation over long runs. Direct-current loop resistance is limited to 4.95 Ω/km at 20 °C, which minimizes voltage drop between inverter and motor. The two control pairs are rated for 300 V according to VDE, so feedback devices or brakes receive stable low-power supply lines inside the same sheath. For fixed routing points, the minimum bend radius is only 5×D, supporting compact cabinet layouts.
In dynamic sections the cable must flex repeatedly; therefore a bend radius of 7.5×D applies in moving drag chains, and the PUR outer jacket resists abrasion while remaining adhesion-free and matte to reduce stick-slip. Eight cores are inside: three power phases plus protective earth use 4.0 mm² conductors approved for up to 300/500 V, while two auxiliary pairs sized 2 × 1.0 mm² and 2 × 1.5 mm² handle sensors or brakes. The design is classified as drag-chain suitable, so cycle counts in the millions are routine.
Wake Industrial stocks the RKL4554 for immediate order fulfillment. Same-day shipping is available when schedules demand quick turnaround. Quotations issued for this cable remain valid for 30 days to aid maintenance planning.
