Application Recommendations
1. -選定のポイント: Choose the appropriate duty cycle based on the load type (AC-3 for motor control, AC-1 for resistive loads)
2. Environmental Considerations: The installation location should be well-ventilated, with an ambient temperature not exceeding 55°C
3. Supporting Protection: It is recommended to use it with appropriate overload protection devices (such as thermal relays) to protect the motor and the contactor itself
4. Cable Selection: For the main circuit, select cables with sufficient cross-sectional area (≥150mm²) to ensure low-impedance connection
5. メンテナンスサイクル: Regularly inspect the contact status; a comprehensive inspection and cleaning at least once a year is recommended
