DY-30 series voltage relay is used in relay protection line as overvoltage protection or low voltage locking starting element, it has the characteristics of plug-in structure, and the inner conductive plate is Ω-shaped spring plate to ensure contact, the relay body can be inserted or pulled out of the relay shell, so as to facilitate use and maintenance.
The DY‑30 series voltage relays are electromagnetic devices used for over‑voltage protection or low‑voltage lockout in protection circuits. The manual lists the applicable models (DY‑31, DY‑32, DY‑33, DY‑34, DY‑32/60C, etc.), their rating ranges and key performance parameters such as voltage settings, contact break capacity and power consumption.
The relays feature a plug‑in construction for easy installation and maintenance, with a metal housing, contact system, adjustment mechanism and mounting brackets. Ordering requires specifying the model, rated voltage and wiring style (full‑wire or rear‑wire). The document also provides dimensions, weight (≈0.6 kg) and durability (500 operations). This manual is written in Chinese.
| 额定电压范围 | 30‑60 V, 35‑70 V, 50‑220 V, 100‑400 V, etc. |
|---|---|
| 触点断开容量 | 250 VA (AC) / 50 W (DC, inductive load) |
| 功率消耗 | 不超过表3所示的最小整定值处的功率 |
| 重量 | 约0.6 kg |
| 耐受动作次数 | ≥500 次 |
When the voltage is ≤250 V and current ≤2 A, the contact can break up to 50 W for inductive DC loads and 250 VA for AC circuits.
The relay can withstand at least 500 operations.
The relay weighs approximately 0.6 kg.
