Product Description:

The RLB2-125JEB belongs to the RLB Motor Power Cables series from Bosch Rexroth Indramat and is used to deliver three-phase power between MS2(X) servo motors and ctrlX DRIVE inverters. As a basic-design cable within the Rexroth Cables product group, it integrates auxiliary conductors for brake or sensor circuits and provides a ready-made solution whenever terminal-box motors must be wired in compact automation cells.

This model is rated for 600/1000 V and its four 16 mm² power cores supply motors drawing up to 71.3 A. The generous copper cross-section of 16.0 mm² limits voltage drop over long runs, while the conductor insulation can tolerate a fixed-installation temperature of 90 °C so cabinet hotspots do not compromise service life. These parameters permit the cable to carry continuous motion currents without exceeding permissible thermal limits defined for the PUR jacket and polyethylene insulation system.

An M-side thread size of M50 matches the Rexroth terminal-box gland, eliminating thread adapters during commissioning. Mechanical layout is optimised for static routing with a minimum bend of 5 × D, yet it also remains suitable for drag-chain duty down to 7.5 × D when machines require moderate axis travel. The outer sheath is PUR (orange RAL 2003), providing oil resistance and high abrasion durability in assembly lines and packaging stations where cable wear is common.
