Anwendungshinweise

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 Installationsanforderungen

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, staubig, corrosive gas or heavy vibration environments

4.3 Operation and Maintenance

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

Fehlerbehebung

Fault Symptom	Mögliche Ursachen	Lösungen
Fails to close	1. Undervoltage trip not powered	1. Check control power supply
	2. Mechanical jamming	2. Operate manually several times to clear jam
	3. Fehler der Auslöseeinheit	3. Replace trip unit module
Häufiges Stolpern	1. Überlast	1. Check load current
	2. Kurzschluss	2. Troubleshoot short circuit
	3. Improper trip setting	3. Reset trip settings

Contact ablation	1. Long-term overload	1. Replace with higher-rated breaker
	2. Insufficient breaking capacity	2. Upgrade to higher breaking capacity model
	3. Excessive operating frequency	3. Reduce operation frequency or replace suitable model
Trip unit does not operate	1. Trip unit damaged	1. Auslöser ersetzen
	2. Falsche Verkabelung	2. Check wiring correctness
	3. Excessively low ambient temperature	3. Improve ambient temperature or select low-temperature model
Motor operation mechanism fails	1. Control voltage below 85% Un	1. Check control power supply
	2. Limit switch not reset	2. Manually reset limit switch
	3. Motor fault	3. Replace operating mechanism motor
