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.
Helps to protect electrical equipment from excessive voltage fluctuations in the network. The relay switches off the load when a critical situation occurs. The load supply is resumed after the delay time has ended. Mostly used with contactors (magnetic starter, power relay).
