RLC1-143GDB Bosch Rexroth Indramat

Product Description:

The RLC1-143GDB is a motor power cable produced by Bosch Rexroth Indramat and supplied within the RLC1 Motor Power Cables series. It serves as the primary power link between an Indramat drive controller and a synchronous or asynchronous motor in automated machinery, carrying three-phase energy and protective earth in one assembly. By matching the electrical and mechanical interfaces defined for the RLC1 series, the cable streamlines installation and ensures that drive modules receive stable current without additional field wiring adjustments.

The four phase cores of the cable are dimensioned to carry up to 38.2 A continuously, allowing medium-power axes to operate without thermal overload of conductors. Each power core has a cross-section of 6.0 mm², which limits resistive losses and keeps voltage drop within the tolerance of servo drives. For users accustomed to American wire tables this corresponds to 10 AWG, simplifying conductor size comparisons when designing mixed-standard panels. The specification lists 4 individual power conductors, so three phases and the protective earth are routed in one sheath. A maximum installed length of 75 m is permitted; beyond this distance cable impedance can distort the drive’s PWM output and reduce motor torque at speed.

An integrated signal bundle supplies feedback devices through 4x 1.0 mm² + 2x 1.5 mm² auxiliary cores, keeping encoder supply and brake lines in the same harness as the main supply. Mechanical retention at both ends relies on a Double clamping system that secures the shield and jacket against tension or vibration. The motor-side plug is sized to the industry standard M40 thread, enabling tool-free coupling with Indramat motor receptacles. Classified as the Basic design variant, this cable omits additional armor or liquid-tight features, targeting cabinet-protected or conduit-routed installations where external mechanical hazards are minimal.
