The image presents a close-up, matter-of-fact view of an electrical installation, specifically focusing on a ZUBR D63t voltage monitoring and protection relay mounted within an electrical panel. The device, colored white, prominently displays "228 V" in red seven-segment LED digits, indicating the current line voltage. Below the voltage reading, two green LED indicator lights are illuminated; one is positioned next to a symbol resembling a circuit breaker or power switch, and the other next to a horizontal three-bar "menu" icon. The relay's specifications are printed on its lower face, detailing its operational range as "100-420 V ~ 50 Hz" and its capacity as "13 900 VA 63 A". Three circular white buttons are visible on the right side, accompanied by symbols: an upward arrow with a plus sign, three horizontal bars, and a downward arrow with a minus sign, suggesting control or adjustment functions. To the immediate left, a portion of another white electrical component, likely a circuit breaker, is visible, marked with "C32" and an incomplete circuit diagram. A yellow-orange lever or toggle is present on this adjacent device. Electrical wiring, including a white insulated cable looping across the top portion of the frame and a yellow-green striped ground wire on the far right, is evident. Screw terminals, labeled '1', '2', and '3', with associated electrical symbols, are visible at the bottom edge of the ZUBR D63t. The background appears to be an indistinct grey surface, consistent with the interior of an electrical enclosure. This specific ZUBR D63t device is manufactured by Novatek-Electro, a Ukrainian company. Such voltage protection relays are commonly installed in residential and commercial premises across Ukraine, including in the city of Kyiv, to safeguard electrical equipment from power surges, sags, and other voltage irregularities. Their widespread use increased significantly following targeted attacks on Ukraine's energy infrastructure, which led to heightened grid instability and the need for enhanced electrical protection for citizens. The displayed 228V falls within the normal operating range for a 230V nominal single-phase AC supply, typical of the Ukrainian electrical grid.
