EOS Power Box for Traditional Sauna Controls
The EOS Power Box is the heart of an EOS sauna control system. While the wall-mounted control provides the user interface, the Power Box contains the electrical switching equipment that safely manages power delivery to compatible sauna heaters, lighting, ventilation, and connected accessories.
Available in multiple electrical configurations for residential and commercial installations, the EOS Power Box can be matched to single-heater and multiple-heater systems in both 9 kW and 15 kW capacities.
Designed Specifically for EOS Sauna Control Systems
Unlike a standard electrical disconnect or contactor, the EOS Power Box is engineered specifically for traditional electric sauna systems. It works together with compatible EOS control panels to manage heater operation, safety monitoring, cabin lighting, ventilation, sensors, and expansion modules.
Every installation begins by selecting the correct Power Box based on heater capacity, available electrical service, and the number of heaters being controlled.
Residential Applications
Available in compatible 240V / 2PH configurations for many residential sauna installations using single or multiple heaters.
Commercial Applications
Commercial facilities commonly utilize compatible 208V / 3PH Power Boxes designed for larger sauna systems and higher electrical demands.
Expandable Design
Compatible with EOS controls, Power Extension Boxes, App Modules, lighting controls, ventilation systems, and approved safety equipment.
Choose the Correct Power Box
This product includes multiple Power Box configurations. Select the combination that matches your sauna system requirements.
| Selection | Options |
|---|---|
| Heater Control Type | Single Heater or Multiple Heaters |
| Kilowatt Rating | 9 kW or 15 kW |
| Voltage / Phase | 240V / 2PH or 208V / 3PH Commercial |
Important: The correct Power Box depends on the sauna heater, electrical service, number of heaters, total connected load, and overall sauna design. If you are unsure which configuration is required, contact My Luxury Home Spa before placing your order.

Selecting the Correct EOS Power Box
Every EOS Power Box performs the same primary function by safely switching power between the electrical service and the sauna heater. The correct model is determined by four primary factors:
Number of Heaters
Determine whether your sauna uses a single heater or multiple heaters operating from one control system.
Heater Capacity
Choose a Power Box designed for either 9 kW or 15 kW heater systems.
Electrical Service
Select the proper voltage and phase configuration based on the available electrical service at the installation site.
Application
Residential and commercial sauna systems often require different electrical configurations and switching capacities.
Understanding Heater Configurations
EOS offers Power Boxes for both single-heater and multiple-heater sauna systems. Selecting the proper configuration ensures safe operation and proper communication between the sauna control and connected equipment.
Single Heater Systems
Designed for one compatible sauna heater connected to a single EOS control system. This is the most common configuration for residential installations and many smaller commercial projects.
- One sauna heater
- Simpler installation
- Available in 9 kW and 15 kW configurations
- 240V or 208V models available
Multiple Heater Systems
Designed for larger sauna rooms where more than one heater is required to achieve the desired heating capacity. These systems require a compatible multiple-heater Power Box and may also utilize Power Extension Boxes depending on system size.
- Supports multiple heaters
- Ideal for larger sauna rooms
- Common in commercial installations
- Expandable with compatible EOS accessories
Choose the Correct Heater Capacity
The Power Box must match the electrical requirements of the connected sauna heater system. Using the incorrect Power Box can prevent proper operation and may require replacement before installation can be completed.
| Power Box Rating | Typical Application | Available Configurations |
|---|---|---|
| 9 kW | Small to medium traditional sauna systems |
Single Heater or Multiple Heater 240V / 2PH or 208V / 3PH |
| 15 kW | Larger residential and commercial sauna systems |
Single Heater or Multiple Heater 240V / 2PH or 208V / 3PH |
The Power Box rating should always correspond to the connected heater system. If multiple heaters are installed, total connected load and overall system design should be reviewed before selecting the appropriate Power Box.
240V Residential and 208V Commercial Models
EOS manufactures Power Boxes for different electrical services. Selecting the proper voltage and phase configuration is essential for compatibility with the sauna heater and building electrical system.
240V / 2PH
Designed for compatible installations utilizing 240-volt electrical service. Commonly selected for residential sauna projects and certain light commercial applications.
- Compatible 240V systems
- Available for 9 kW and 15 kW
