In the absence of explicit instructions, the load current marked on the housing of all Wanjia Star relays is a resistive load. Under the rated switching voltage, the allowable current of the inductive load should not exceed 30% of the rated resistive load, the allowable current of the motor load should not exceed 20% of the rated resistive load, and the allowable current of the lamp load should not exceed the rated resistive load. 10% of the load, the allowable current of the capacitive load should not exceed 5% of the rated resistive load. For the reliability of the actual use of the product, it is recommended that the contact load current value not exceed 60%-70% of the steady-state current value under the rated load of the product when selecting the model.
The reference values of inrush current under different load types are shown in the table below:
Precautions
1. Do not touch the terminal part of the relay and the connected electrical accessories when it is powered on. Please cut off the power supply when installing and maintaining the relay (including terminal blocks, sockets and other connecting parts). Please contact us for technical support.

2. Do not use the relay beyond the rated load. Overload use may cause insulation performance degradation, contact adhesion, poor contact and other failures, and even cause damage to the relay itself, burnout and electric shock.

3. Please avoid dropping the product during storage and use, and do not disassemble the internal components. In order to avoid damage, burn and electric shock.

4. Do not use it in an environment with flammable or explosive gas. And avoid using it in places where there is water, steam, melting after freezing or water droplets falling.

5. All the rated performance values in the product information are the values under the standard test state unless otherwise specified. When using an actual device, in addition to the load conditions, the usage environment must also be confirmed under the same conditions as the actual usage status.

6. The relay coil has polarity (the positive and negative poles are marked on the circuit diagram). When connecting the terminals, please refer to the wiring diagram and then connect them correctly. Situation happens.

7. Avoid continuously applying voltage to the coil that exceeds the maximum switching voltage.
