Installation und Wartung
Wichtige Installationspunkte
- Vertikale Installation: The inclination angle should not exceed 5° to ensure good heat dissipation
- Electrical Connection:
Main circuit: 6~25mm² singlestrand hard wire or 6~16mm² flexible wire
Control circuit: 1.5~2.5mm² wires
Tightening torque: 3.5N·m for the main circuit and 0.8N·m for the control circuit
- Heat Dissipation Space: Ensure sufficient ventilation space around the contactor
Wartungsempfehlungen
Regelmäßige Inspektion:
Check if contacts are ablated or deformed
Check if connections are loose
Remove dust and foreign objects
Maintenance Cycle:
Lowfrequency use (<15 operations/hour): Inspect once a year
Highfrequency use (>15 operations/hour): Inspect every 13 months
Selection Considerations
- Selection Based on Load Type:
Slightly inductive loads such as lighting and heating: Select the rated current for AC7a (63A)
Motorlasten: Select the rated current for AC7b (20A)
Mixed loads: Select according to the most severe conditions
- Selection Based on Voltage and Pole Number:
Singlephase loads: 2P model
Threephase loads: 3P model
Threephase + neutral line system: 4P model
The control voltage must be consistent with the system (usually 220~240V AC)
- Selection Based on Contact Configuration:
Only need to turn on/off: Select NO (Normalerweise geöffnet) Kontakte
Need status feedback: Select NO+NC combination
Special safety control: Select NC (Normalerweise geschlossen) Kontakte
