Power cable Rittal DK 7856.025, 3 m, multicolour, 3-phase 5‑pole 16 A

Rittal DK 7856.025 is a preassembled multicolour power cable, 3 m in length, intended for three‑phase electrical connections at 16 A. The 5‑pole configuration supports three live conductors plus neutral and earth, making it suitable for supplying switchgear, control cabinets and industrial equipment where a compact, clearly marked cable is required. Colour coding of individual conductors simplifies identification during installation and maintenance.

Advantages

The 3 m length provides a balance between reach and cable management in typical control cabinet and machinery installations. A 5‑pole, 16 A rating meets common requirements for small to medium three‑phase loads. Preassembled termination reduces installation time and potential wiring errors compared with field‑assembled cables. Multicolour conductors improve wiring clarity and make fault tracing faster.

Suitable for

• Connecting Power System Modules and switchgear in industrial control panels
• Supplying three‑phase motors and small distribution units requiring 16 A
• Temporary or permanent connections inside control cabinets and machinery enclosures

When it may not be suitable

This cable is intended for three‑phase systems with a 16 A current rating; it is not suitable for applications requiring higher current capacity or different pole arrangements. It is designed for internal cabinet and enclosed equipment wiring rather than long external runs or direct burial without additional protection.

Key specifications

• Length: 3 m
• Number of poles: 5 (three phases, neutral, earth)
• Rated current: 16 A
• Configuration: 3‑phase
• Conductor identification: multicolour
• Connector type: preassembled male terminations

How to use

Verify the installation location and ensure power is isolated before connecting. Route the Rittal DK 7856.025 cable from the Power System Module or distribution block to the equipment terminal strip, observing bend radii and securing the cable to prevent strain on connectors. Match conductor colours to terminal designations (L1, L2, L3, N, PE) and tighten connections to the torque values specified by the equipment manufacturer. Perform insulation and continuity checks before reapplying power.

What to consider before purchase

• Confirm the required current rating (16 A) and that a 5‑pole, 3‑phase cable meets your load and wiring scheme
• Ensure 3 m length is sufficient for your routing; consider longer cables or additional routing accessories if needed
• Check connector compatibility with your Power System Module and terminal types
• Assess whether installation conditions require additional protection (conduit, glands, or external-rated cabling)

Usage recommendations

Use the multicolour conductor coding to maintain consistent phase identification throughout your system. Secure the cable near terminations to avoid mechanical stress and periodically inspect connections for tightness and signs of wear in routine maintenance.
