- Application Notes
4.1 إرشادات الاختيار
Suitable for motor protection and general industrial power distribution systems, especially where D-curve tripping is required
Derate when ambient temperature exceeds 40°C: 1% per °C rise; max operating temperature 60°C
Derate at altitudes above 2000m: 1% per 100m rise; max altitude 4000m
Select appropriate trip setting current according to actual load, ensuring I_load ≤ In ≤ I_cable
4.2 متطلبات التثبيت
Ensure breaker is OFF and voltage-free with multimeter before installation
Mount on 35mm standard DIN rail, ensure firm fixing to avoid vibration effects
Tighten terminals with suitable torque (recommended 6N·m) to prevent overheating from poor contact
Keep sufficient heat dissipation space: at least 50mm clearance around the breaker
Avoid installation in damp, مغبر, corrosive gas or heavy vibration environments
4.3 التشغيل والصيانة
Inspect mechanical operating mechanism regularly (annually recommended) to ensure smooth ON/OFF
Test tripping function regularly (semi-annually recommended) to ensure reliable protection
Clean surface with dry soft cloth; avoid chemical cleaners
Record operation count; replace before reaching mechanical endurance
After short-circuit interruption, check breaker condition and replace if necessary
