One relay can protect millions in equipment
In industrial reality, the most expensive breakdowns often start with the cheapest undetected fault. That is why a properly chosen relay is not an expense — it is the most profitable insurance policy your production can have.
Who we are
ПрофЕлектроГруп exists to make industrial electrical protection understandable, accessible and predictable. For years we have been helping factories, boiler houses, water utilities, elevators, food processing plants and machine-building enterprises choose equipment that works reliably for 7–12 years without surprises. Our principle is simple: sell only what we understand deeply and would use ourselves.
