| 3. Faulty tripping mechanism | 3. Check tripping mechanism and replace if needed |
6.2 Maintenance Procedures
- Daily Inspection (Weekly)
Check knob position and status indication
Look for abnormal heat, odor or noise
Confirm all terminals are tightly connected
- Routine Maintenance (Every 6 Months)
Power off and remove dust with dry compressed air
Inspect main contacts for burning and oxidation
Test tripping function by simulating overload and short circuit conditions
- Annual Maintenance
Check lubrication of internal mechanical components
Verify accuracy of current setting
Retighten all electrical connections
6.3 Quick Diagnosis Tips
Thermal trip? Check load and current setting.
Magnetic trip? Locate short circuit and test insulation.
Fail to close? Reset first; replace for mechanical faults.
No output? Inspect contacts and wiring.
- Selection & Installation Guidelines

Current Matching: Motor FLA must fall within 24-32A; recommended setting: FLA × 1.1
Power Matching: Standard solution for 15kW @ 400V three-phase motors
Protection Coordination: Use with contactors and fuses to ensure selective protection
Ambient Derating: Derate 1% per ℃ above 40℃
7.2 Installation Notes
Mounting Direction: Vertical installation (allowable deviation: ±15°) for normal tripping operation
Clearance: Reserve 10mm space on left & right sides, 20mm on top & bottom for heat dissipation
Wiring Standard: Copper wire with cross-section 1.5-25mm²; tightening torque: 6-8Nm
Locking Function: Padlock can be fitted to prevent accidental operation, complying with safety regulations
