Modern appliances are an investment you want to keep for years. But fluctuations in the power supply can damage expensive electronics. That’s why ZUBR voltage relays are a smart choice to protect your devices from power surges.

ZUBR voltage relays constantly monitor the voltage level in the power supply. If a dangerous fluctuation is detected — whether an increase or a drop — the device instantly cuts off the power to prevent damage to connected appliances. Once the voltage stabilizes, the relay activates a delay timer to ensure the network is steady. Only after that is power restored, helping to avoid repeated failures caused by brief power disturbances. Read more

Why is dry contact important for boiler control?
To control a boiler, the external thermostat's output contacts must not carry 230 V power. When choosing a thermostat for a boiler, ensure it features a dry contact and that the boiler's schematic permits connection to an external thermostat.

In the terneo pro dry contact thermostat, the dry contact is implemented with a separate contact group, ensuring no voltage is present on the output terminals in any state. The "dry contact" prevents 230V power from reaching the boiler control terminals (5 and 6) from terminals 3 and 4 of the thermostat. Read more
