Single-phase voltage relay ZUBR D50t, DS Electronics, (4820120220470)
General description of D25t-63t series single-phase voltage relays Zubr
ZUBR D25t-63t voltage relays are designed to protect equipment from excessive voltage fluctuations in the network. In the event of an emergency, the relay disconnects the load. It is used in single-phase AC networks (230 V).
After voltage stabilization, the voltage delay timer is activated. You can adjust its duration from 3 to 600 s. For equipment sensitive to frequent power outages (eg refrigerators, air conditioners and heat pumps), the recommended delay time is 120-180 seconds.
Component reliability and operational safety
The body of the devices is made of non-flammable polycarbonate. This increases the safety when using the relay. And the use of German EPCOS capacitors in circuitry extends the service life by 3-4 times in comparison with analogues of other manufacturers.
The device is controlled with just three buttons. The digital screen displays voltage value and system information. It helps to easily set the upper and lower voltage limits and also makes menu navigation easier.
The voltage relay is installed in a distribution box on a standard 35 mm DIN rail. The terminals of the device provide reliable contact in the power section of the housing.
