ZUBR S6 ensures an uninterrupted power supply to priority single-phase equipment in a three-phase network with unstable voltage. The phase selector chooses the best phase — priority equipment operates:
- for business processes (medical, refrigeration and retail equipment, server rooms, POS systems)
- for personal needs (lighting, heating, computers, electric vehicle charging stations, ventilation, etc.)

Stable power supply of priority equipment
How the phase switch works: the device constantly monitors the voltage across all three phases (L1, L2, L3). If the voltage on the phase supplying the priority equipment exceeds the set limits or drops to zero, ZUBR switches the power supply for that equipment to another stable phase. And, of course, it protects your equipment from critically high and low voltages.
Examples of priority equipment
✔ For business operations — medical equipment, refrigeration and retail equipment, server rooms, POS systems
✔ For personal needs — lighting, heating, computers, EV charging stations, ventilation — everything that matters most to you
High switching speed
High switching speed is a key advantage of the ZUBR S6. This parameter often determines whether a switch is suitable for a particular application. The ZUBR S6 ensures the uninterrupted operation of your critical equipment thanks to its phase-to-phase switching speed of 0.1 seconds.
Automatic and manual phase priority selection
You can manually set the phase priority (any combination of the sequence of all three phases: 123, 132, 213, 231, 312, 321). In «oFF» mode, the device automatically detects the most stable phase and switches the load to it in the event of a fault.
To view, hold the «i» button for 3 seconds. Phase priority settings are described in the table under the «Pri» menu item.
The standard ZUBR features are included:
— protection against high and low voltage for priority equipment;
— monitoring of mains quality via the Log of events;
— flexible post-fault delay settings;
— advanced settings (Pro mode, hysteresis and others);
— thermal protection.
Easy installation
ZUBR S6 phase selector occupies 6 standard modules in a distribution board on a standard 36 mm wide DIN rail. The busbar for connecting the common neutral can be replaced with a longer one, for example, one shared with the circuit breakers. If the room has high humidity or there is a risk of water coming into contact with the device, the panel must comply with protection class IP20 (in accordance with DSTU 14254).
