▍Product features
Step 1: Installation
Ensure the 400A contactor is mounted securely in a dry, vibration-free environment. This model is designed for installation in compact spaces, so it’s important to check for proper ventilation to prevent overheating.
Step 2: Wiring
Follow the product's wiring diagram closely. Ensure the correct connection of the 12/24/48V control coil to the system. Improper wiring can result in operational failures.
Step 3: Testing
After installation, run a system test to check for normal contactor operation. Monitor the contactor for any irregular noises or signs of overheating during the initial test run.
Step 4: Regular Maintenance
Perform routine inspections to ensure all connections remain secure and clean. Any dust or debris should be cleared to maintain optimal performance. Lubrication is generally not required due to its low-maintenance design.
▍Coil Data
| Coil Voltage | Pickup Voltage | Dropout Voltage | Inrush Current | Avg Holding Current | Holding Power |
| 12VDC | 9VDC Max | 1.2VDC Min | 3.8A Max | 0.5A Approx | 6W Max |
| 24VDC | 18VDC Max | 2.4VDC Min | 2A Max | 0.25A Approx | 6W Max |
Remarks:
1. The coil parameter values are theoretical values at an ambient temperature of 20℃, with a variation range of approximately ±10% due to the influence of coil resistance.
2. The reliable working voltage range of the coil is 85%~110% of the rated voltage.
3. If other rated voltages are required,special orders can be made.
▍Main Contact
