Voltage relay ZUBR D6-40 red

ZUBR D6 red: New generation electrical equipment protection.

ZUBR D6 red is an advanced three-phase voltage relay (3x40 A), designed for comprehensive protection of your electrical equipment from voltage surges and other emergency situations in the network. The device is designed for DIN rail mounting and can work with both three-phase (230/380 Volts) and single-phase (230 Volts) networks, providing a universal solution for a wide variety of objects.

One of the key features of ZUBR D6 red is the TrueRMS function, which ensures accurate measurement of the root-mean-square voltage value, which is critical for the correct operation and protection of sensitive electronics. You can easily adjust the lower voltage limit in the range from 120 to 210 V and the upper limit from 220 to 280 V, which allows you to adapt the relay to the specific requirements of your electrical network.

The relay is equipped with a professional shutdown delay, which minimizes false alarms during short-term interference. In case of a significant voltage drop (less than 120 V), shutdown occurs almost instantly (no more than 0.04 s), and in case of voltage excess - also instantly. For less critical voltage drops (more than 120 V), the shutdown time is adjustable from 0.1 to 10.0 s. For safe resumption of equipment operation, a load switching delay with a wide range of settings from 3 to 999 seconds is provided.

ZUBR D6 red also has built-in thermal protection that prevents overheating of the device, and a phase imbalance (asymmetry) control function with an adjustable threshold from 10 to 80 V and shutdown time from 0 to 30 s. This provides an additional level of protection for three-phase motors and other equipment sensitive to phase imbalance.

With a rated load power of up to 3 x 8,800 VA , this relay is capable of withstanding significant loads. Compact dimensions (106 x 85 x 66 mm) and light weight (0.43 kg) facilitate installation in panels. High reliability is confirmed by a resource of 10,000 switching operations under load and 500,000 switching operations without load.

Degree of protection according to GOST 14254 - IP20.
