S07RC4N8-F for Pump Connections
S07RC4N8-F is a 450/750 V screened rubber cable for submersible wastewater pumps and frequency-converter-controlled motors. It combines EPR-insulated conductors, an overall tinned-copper braid and a black CPE outer sheath.
The four-core G configurations include a protective conductor as well as the phase conductors. The braid provides the EMC screening function and is not a substitute for the PE connection. Effective screen contact at both cable ends should be planned with the drive, motor and cable-entry system. Keep the braid termination accessible and mechanically protected during installation.
The size table covers 4G1.5 through 4G120, with separate minimum and maximum finished diameters and approximate masses. Use the whole diameter range when choosing a gland or sealing sleeve. A screened cable has a different outside diameter and termination build from an unscreened lead of the same conductor section.
Give the drive output, motor current, installed length and routing with the enquiry. These inputs help coordinate conductor sizing, screen termination and the available bending space. Provide independent cable supports and include the wastewater composition when selecting the sheath and accessories. Immersion depth and water-temperature limits are confirmed for the specified installation.
- Keep the braid and protective conductor as separate connection functions.
- Select the seal from the finished OD limits of the exact 4G configuration.
- Allow space for screen preparation, strain relief and the specified bend.

Applications
S07RC4N8-F is a 450/750 V screened rubber cable for submersible wastewater pumps and frequency-converter-controlled motors. It combines EPR-insulated conductors, an overall tinned-copper braid and a black CPE outer sheath.
| Selection point | What to coordinate |
|---|---|
| EMC connection | Provide effective braid contact at both cable ends and a separate PE connection. |
| Entry dimensions | Match the exact 4G size and its OD limits to the gland or sealing sleeve. |
| Drive duty | State drive output, motor-cable length, current and routing for the connection design. |
| Bending space | Allow the required radius beyond the prepared screen termination and strain relief. |
Confirm immersion depth and the maximum permitted water temperature with the enquiry. Support the cable independently; use a separate mechanical system to lift the pump.
