Product Description:

The RKL4331 is a ready-made motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. This component links a servo controller to its matched motor, transferring three-phase power and protective earth in automated machinery. Preterminated connectors and controlled assembly dimensions help simplify installation in moving equipment. The cable is suited for dynamic motion axes used on gantries, packaging lines, and handling modules where repeatable routing and stable electrical performance are important.

The mechanical fatigue rating reaches 5,000,000 flex cycles, indicating how many bend reversals the jacket and conductors can tolerate during continuous machine operation. During movement, the cable should follow a carrier system, and its dynamic bend radius is 7.5 x D. In fixed routing, the cable may be curved to 5 x D without overstressing the copper cores. Its operating temperature range extends from -30 °C to 80 °C, which supports both cold-start conditions and elevated cabinet temperatures while helping protect the insulation during normal service.

Electrical capacity is based on a power core cross-section of 25.0 mm² for the main phase current, while auxiliary functions are supported by a separate 1.5 mm² core. The motor end terminates in an RLS1301/C25 connector, and the controller end uses an RLS0723/K25 connector, which removes the need for on-site crimping and maintains pin compatibility with matching drive components. The GNYE protective-earth conductor uses the same gauge as the power conductors, providing the same fault-current capacity along the grounding path. Bulk material code INK0607 is used for the jacket compound and shielding package that help limit leakage current and reduce electromagnetic emission during high-frequency inverter switching.
