Power adapter QOLTEC CEE 16A 5P 400V to SCHUKO 230V, model 52724

The QOLTEC power adapter model 52724 converts a three-phase CEE 5-pin 16A 400V supply to a single-phase SCHUKO 230V outlet. It is intended to allow connection of standard 230V SCHUKO devices to an available CEE 400V socket for temporary use, such as powering tools, appliances or test equipment. The adapter provides a compact interface that routes one phase and neutral from the 400V source to a protected SCHUKO receptacle, enabling use where a dedicated 230V supply is not available.

Advantages

The adapter offers straightforward mechanical and electrical compatibility between widely used industrial CEE sockets and household SCHUKO plugs, with a robust housing suitable for workshop and field environments. Its design simplifies temporary connections without rewiring the installation and reduces the need for separate converters when a single-phase load is required from a three-phase supply. The unit supports safe, limited-duration operation when used within rated current and safety requirements.

Suitable for

• Temporary connection of 230V SCHUKO power tools and appliances to a 400V CEE outlet
• Test and diagnostic equipment that requires single-phase 230V supply
• Workshops, construction sites and service vans where three-phase sockets are available

When it may not be suitable

This adapter does not perform phase conversion or provide true single-phase power balancing; it connects one phase and neutral from a three-phase supply. It is not suitable for continuous heavy loads that approach or exceed the rated current, nor for equipment that requires an isolated transformer, stabilized voltage, or a specific earthing arrangement beyond the adapter's capabilities. Users must verify device current draw and compatibility before use.

Key specifications

• Input type: CEE 5-pin 3-phase socket, 16 A, 400 V
• Output type: SCHUKO (Type F) single-phase outlet, 230 V
• Nominal current capacity: 16 A (subject to device and installation limits)
• Typical power capability: up to approximately 3.5 kW on a single phase (dependent on installation and safety margins)
• Enclosure: durable plastic housing suitable for workshop use

How to use

Connect the adapter by firmly plugging the CEE 5-pin plug into the corresponding 16A 400V socket, ensuring correct insertion and that protective interlocks (if present) are engaged. Plug the SCHUKO device into the adapter's outlet, confirm the device's rated voltage and current do not exceed the adapter's capacity, and switch on the supply only after all connections are secure. Monitor the adapter and connected equipment during initial operation for overheating or unexpected behavior. Disconnect power before making or removing connections.

What to consider before purchase

• Verify that your device's current draw and power rating are within the adapter's single-phase capacity.
• Confirm that a simple phase-to-SCHUKO connection meets legal and site safety requirements for your installation.
• Check grounding and earthing compatibility between the CEE supply and the SCHUKO device.
• Consider whether a transformer or dedicated single-phase supply is required for sensitive or continuous loads.

Recommendations

Use the adapter only for temporary connections and intermittent operation. For continuous or high-power applications, install a dedicated single-phase supply or use an appropriate phase converter or transformer. Ensure periodic visual inspection for wear, secure contacts, and correct earthing before each use.
