Model Description
Contact parameters
| Contact type | 2Z,2H,2D |
| Contact load | 30A |
| Maximum switching voltage | 28VDC 30A 240VAC30A |
| Contact Material | Silver alloy |
Contact Type Description
Transformational:In the middle is the moving contact. When the coil isn’t energized, the moving contact is disconnected from one of the stationary contacts and connected to the other. Once the coil is energized, the moving contact moves, causing the previously disconnected contacts to become connected and the previously connected contacts to become disconnected. This achieves the purpose of switching.
Normally Open Type:The contacts are open when the coil is not energized; the contacts close when energized.
Normally Closed Type:When the coil is not energized, the contacts are closed; when energized, the contacts open.

Selection Guidelines
Unless otherwise specified, all load currents indicated on the relay housings refer to resistive loads. At the rated switching voltage, the allowable current for inductive loads should not exceed 30% of the rated resistive load current. For motor loads, the allowable current should not exceed 20% of the rated resistive load current. For lighting loads, it should not exceed 10%. For capacitive loads, it should not exceed 5%. To ensure reliable operation of the product, it is recommended that the contact load current not exceed 60%–70% of the steady-state current at the rated load.
| 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 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 |
| Transformer 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 |
