Main goal of the voltage monitoring relays is to protect appliances from high and low voltage and neutral wire break. The relay operates on the cutoff principle: if the set values are exceeded, it turns off the load. Brand ZUBR has been on the market for 20 years and is now highly regarded by Ukrainian electricians. And now we are becoming increasingly popular in European Union countries like Poland, Lithuania, Czech Republic, Romania and others.
We invite you to watch a short video review about the ZUBR voltage monitoring relays range on our YouTube.
In single-phase load mode the functions of three-phase relays with independent settings are performed. In three-phase load mode and control common to all power relays, this device will build equipment from exceeding allowable limits and control maximum phasing, phase rotation and phase loss.
ZUBR S6 ensures an uninterrupted power supply to priority single-phase equipment in a three-phase mains supply with unstable voltage. It is suitable for medical, refrigeration and retail equipment, server rooms, point-of-sale systems, as well as lighting, heating, computers, charging stations and ventilation. ZUBR S6 selects the best phase – priority equipment remains operational.
