Unless otherwise specified, all load currents indicated on the Hangwang relay case are for resistive loads. Under the rated switching voltage, the allowable current of inductive loads should not exceed 30% of the rated resistive loads, the allowable current of motor loads should not exceed 20% of the rated resistive loads, the allowable current of lamp loads should not exceed 10% of the rated resistive loads, and the allowable current of capacitive loads should not exceed 5% of the rated resistive loads. In order to ensure the reliability of the product, it is recommended that the contact load current value should not exceed 60% – 70% of the steady state current value under the rated load of the product.
| Nature of the load | Inrush current |
| Resistive load | 1 times the steady-state current |
| Sodium lamp load | 1-3 times the steady-state current |
| Mercury-vapor lamp load | 3 times the steady state current |
| Inductive load | 3-5 times the steady-state current |
| Motor load | 3-5 times the steady-state current |
| Voltage load | 3-5 times the steady-state current |
| Incandescent lamp load | 3-5 times the steady-state current |
| Capacitive load | 3-5 times the steady-state current |
