Power extension cable Rittal DK 7856.014 — 0.5 m, C13 coupler to C14 coupler, 10 A

Rittal DK 7856.014 is a 0.5 m power extension cable with a C13 coupler to C14 coupler layout rated for 10 A. The cable is designed for short power connections between compatible IEC devices in IT and industrial environments, enabling secure power transfer between a C13 (female) inlet and a C14 (male) outlet. Its compact length and standardized connectors make it suitable for use in confined spaces such as server racks, power distribution units (PDUs) and workstations.

Advantages

The Rittal cable provides a ready-to-connect solution with standardized IEC C13 and C14 connectors, ensuring compatibility with widely used server and networking equipment. At 0.5 m length it reduces cable clutter and improves airflow management in racks while maintaining a rated current of 10 A for reliable low-voltage power delivery. The black jacket offers a neutral appearance that integrates with most equipment layouts.

Suitable for

• Short power connections in server racks and cabinet PDUs
• Connecting IT equipment such as servers, switches and routers to power outlets with matching IEC connectors
• Power handover between devices during maintenance or reconfiguration
• Workstations and lab equipment requiring a short IEC extension

When it may not be suitable

This 0.5 m cable is intended for short runs; it is not suitable where longer reach is required. It is rated to carry up to 10 A and therefore is not appropriate for high-current applications or equipment that requires higher rated cables.

Key specifications

• Length: 0.5 m
• Connector 1: IEC C13 (female coupler)
• Connector 2: IEC C14 (male coupler)
• Rated current: 10 A
• Colour: Black
• Application: Short IT and industrial power connections

How to use

Plug the C14 male coupler into a matching C14 inlet on the power source or PDU, and insert the C13 female coupler into the device power inlet. Ensure both connectors seat firmly and that the cable is routed to avoid strain or sharp bends. Verify that the connected equipment’s power requirements do not exceed the cable’s 10 A rating before powering on.

What to consider before purchase

• Required cable length — 0.5 m is intended for short connections
• Connector compatibility — verify devices use IEC C13 and C14 connectors
• Current rating — ensure 10 A is sufficient for your equipment
• Environment — check that cable jacket and routing meet your installation conditions

Usage recommendations

Use the Rittal DK 7856.014 for tidy, short-distance power connections inside racks and cabinets. Avoid exceeding the 10 A rating, prevent sharp bends near the connectors, and secure the cable to prevent mechanical strain during maintenance or reconfiguration.
