Single phase voltage relay

Single phase voltage relay ZUBR D16 helps to protect electrical equipment from excessive voltage fluctuations in the network. The device switches off the load when a critical situation occurs. You can select an upper voltage limit in the range of 220 to 280 V and a lower voltage limit in the range of 120 to 210 V. The relay also protects from a break of zero wire on the electric line while its entry into the phase. The model is mostly used with contactors (magnetic starter, power relay).

When an emergency occurs in the network, the relay disables the load supply until the voltage is fully stabilized.

Load delay timer

After the voltage is stabilized, the relay resumes load supply after a preset delay time. You can set the delay duration from 3 to 600 seconds (step 3 seconds) by yourself. For compressor equipment, such as refrigerators and air conditioners, we recommend setting its duration at 120-180 s.

Easy settings

The device is operated by only three buttons. The digital screen displays the voltage value and system information. It allows to easily set the upper and lower limit of permissible voltage. The screen also simplifies menu navigation.

The housing has a green indicator that signals the voltage supply.

Simple installation

The voltage relay ZUBR D16 is installed in the switchboard on a standard 35 mm wide DIN rail. If there is a possibility of water entering the device in the room, then the board should have an IP55 protection class as per 14254 GOST.
