Power distribution unit Rittal 7979.142 42×C13 3 m cable 230 V 16 A Three-phase Black 0U

Rittal 7979.142 is a basic 0U rack-mount power distribution unit (PDU) that delivers centralized three-phase 230 V power distribution through 42 C13 outlets. Designed for installation in server cabinets and network racks, this PDU features a fixed 3 m supply cable and a 16 A nominal current rating, supporting up to approximately 11,000 W of total power capacity when used with appropriate three-phase supply configurations. The unit’s black finish and slim 0U form factor allow installation without consuming vertical rack space.

Advantages

The PDU provides high outlet density with 42 C13 sockets to serve multiple servers, switches and other IT equipment from a single, rack-mounted device. Its 0U mounting saves usable rack space compared with vertical or horizontal units that occupy rack units. A 3 m supply cable eases connection to nearby power feeds without additional extension cords, and the 16 A rating ensures compatibility with common three-phase 230 V rack power supplies. The basic design focuses on reliable, passive power distribution without complex electronics or management overhead.

Suitable for

• Server cabinets and network racks in data centers or small server rooms
• Racks requiring many C13 outlets for servers, switches, storage and peripherals
• Environments where a compact 0U solution is needed to preserve rack U space
• Setups with a three-phase 230 V supply and a 16 A input circuit

When it may not be suitable

This basic PDU does not include outlet-level metering, remote management, switched outlets or surge protection, so it may not meet needs for remote power control, individual outlet monitoring or advanced power management. For environments that require networked monitoring, scheduled power cycling, or integrated surge suppression, a managed or protected PDU would be more appropriate.

Key specifications

• Input voltage: 230 V (three-phase)
• Maximum current: 16 A
• Power capacity: up to approx. 11,000 W (dependent on supply configuration)
• AC outlet count and type: 42 × C13
• Form factor: 0U rack-mount
• Design: basic passive PDU (no integrated metering or switching)
• Colour: Black
• Cable length: 3 m fixed supply cable

How to use

Install the Rittal 7979.142 in a compatible 19" server rack using the 0U mounting points specified by the rack manufacturer so that the unit occupies no vertical rack units. Route the 3 m supply cable to a suitable three-phase 230 V power outlet or distribution block protected by a 16 A circuit breaker. Plug equipment power cords into the C13 outlets, observing power distribution across phases as required by your rack’s power plan. Because the PDU is passive and unmanaged, there are no configuration settings; ensure load balancing and total current do not exceed the supply rating.

What to consider before purchase

• Confirm rack compatibility and available 0U mounting points in your cabinet
• Verify your facility supply is three-phase 230 V and a 16 A input is appropriate
• Check total connected equipment power to avoid exceeding the PDU’s current rating
• Decide if you need metering, switched outlets or surge protection — this basic model lacks those features

Usage recommendations

Distribute high-draw devices across phases to balance load, secure cables to prevent strain on the fixed supply lead, and document outlet assignments to simplify maintenance. For remote monitoring or individual outlet control, consider pairing this unit with separate monitoring equipment or selecting a managed PDU.
