To protect a specific group of consumers. Installed in the switchboard.
The Zubr D16 single-phase voltage relay helps protect electrical equipment from excessive voltage fluctuations in the network. The device disconnects the load when a critical situation occurs. You can choose the upper voltage limit in the range from 220 to 280 V and the lower one - from 120 to 210 V. The relay also protects against breakage of the neutral wire on the power line with its falling into the phase. The model is most often used with contactors (magnetic starter, power relay).
In the event of an emergency situation in the network, the relay turns off the load supply until the voltage is fully stabilized.
Load Delay Timer
After the voltage stabilizes, the relay will resume supplying the load after the set delay time. You can independently set the duration of the delay from 3 to 600 s (step 3 s). For compressor equipment, such as refrigerators and air conditioners, we recommend setting its duration to 120–180 s.
Easy parameter setting
The device is controlled by only three buttons. Digital screen displays voltage value and system information. With it, you can easily set the upper and lower limit of the allowable voltage. The screen also simplifies menu navigation.
The case contains a green indicator that signals the supply of voltage.
Easy Installation
The ZUBR D16 voltage relay is mounted in a switchboard on a standard DIN rail 35 mm wide. If there is a possibility of water ingress on the device in the room, then the shield must have an IP55 protection class in accordance with GOST 14254.
