NJB1-Y single-phase voltage relay is suitable for control circuits with AC voltage of 220V, 110V, 24V, frequency of 50Hz and DC voltage of 24V, as a single-phase overvoltage protection or undervoltage protection, indicator element, with technical performance such as action setting range, action time, repetition accuracy, time error, etc.
The NJB1-Y single‑phase voltage relay is designed for use in control circuits with AC voltages of 24 V, 110 V, 220 V and DC 24 V, offering over‑voltage and under‑voltage protection. It can be powered from a range of control voltages and includes configurable input thresholds.
The manual lists the relay’s technical parameters such as contact capacity (Ue/Ie AC‑15 220 V/0.75 A, 120 V/1.5 A), power consumption (≤3 VA), response time (≤0.1 s), and mechanical life (50 000 make / 30 000 break cycles). Installation options include DIN‑rail mounting or device‑type mounting, and detailed wiring diagrams are provided. This manual is written in Chinese.
