Application Notes

4.1 Selection Guidelines

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 Cerințe de instalare

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, prăfuită, corrosive gas or heavy vibration environments

4.3 Operare și întreținere

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
