JL5 type current relay is mainly used in control circuits of AC voltage 380V and below and DC voltage 440V and below. It is mainly used on magnetic control devices or protection switch panels as overcurrent and short circuit protection for AC and DC motors.
The JL5 series AC/DC current relay is intended for overload and short‑circuit protection of AC motors (≤380 V) and DC motors (≤440 V). It is mounted on magnetic controllers or protection switch panels and operates under specified environmental limits.
The manual lists normal operating conditions (altitude ≤2000 m, temperature –25 °C to +40 °C, humidity up to 90 %), coil technical values for various coil numbers, user adjustment instructions, contact pressure specifications, wiring recommendations, and physical dimensions for installation. This manual is written in Chinese.
| Adjustment range (A) – Coil 1 | 900 |
|---|---|
| Contact pressure (g) | 100‑150 |
| Maximum operating altitude (m) | 2000 |
The relay can be used at altitudes up to 2000 m.
Copper washers and copper nuts should be used on the side where current passes to ensure good contact.
The contact pressure should be between 100 g and 150 g.
