Product Description
EOS 400 V 3N to 230 V 1N Connection Adapter – Single-Phase Power Supply for Compatible Sauna Heaters
The EOS connection adapter 94.2689 enables suitable sauna heaters normally designed for a three-phase 400 V 3N connection to operate on a single-phase 230 V 1N electrical supply.
This distribution unit is designed for compatible electric sauna heaters with a maximum heating output of 9 kW. Three integrated 16 A fuses provide protection for the individual circuits.

Technical Features
Electrical Connection
The adapter is intended for a 230 V 1N AC single-phase electrical supply. It distributes power to the relevant circuits of compatible sauna heaters and controllers.
It is not a voltage converter and does not generate a three-phase 400 V supply.
Integrated Fuses
The unit includes three integrated 16 A fuses. The main supply circuit must also be correctly rated and protected according to the total electrical load and applicable regulations.
Sauna Heater Compatibility
The EOS connection adapter is suitable for electric sauna heaters up to 9 kW only when the manufacturer explicitly permits single-phase 230 V operation.
The sauna controller must also support the corresponding electrical connection.
Important Electrical Installation Information
A 9 kW sauna heater operating at 230 V draws approximately 39 A. The electrical installation therefore requires appropriately sized cables, suitable circuit protection and sufficient supply capacity.
Important: Three integrated 16 A fuses do not mean that a 9 kW sauna heater can be connected to a standard 230 V socket protected by a 16 A circuit breaker.
Installation and commissioning must be carried out exclusively by a qualified electrician.
