- Status Visualization: MicroLogic 2.2 is equipped with LED display for real-time monitoring of current and fault status.
- Modular Design: Supports a variety of accessories (auxiliary contacts, alarm contacts, undervoltage release, etc.) for flexible installation.
- Environmental Friendly: Schneider Green Signature design, reducing energy consumption and carbon footprint.
- Easy Operation: Ergonomic handle for labor-saving operation; front-mounted accessories reduce wiring time by 40%.
- Application Scenarios
- Industrial Power Distribution Systems: Used as main switch or branch switch to protect motors, transformers and distribution lines.
- Building Electrical Systems: Low-voltage distribution cabinets in commercial buildings and industrial plants.
- Motor Control Centers (MCC): Protect three-phase motors from locked rotor and overload conditions.
- Data Centers: Power protection for critical loads to ensure power supply continuity.
- New Energy Sector: DC-side protection of photovoltaic inverters and energy storage systems (additional configuration required).

Comparison with Chint Alternative Models
| Schneider Model | Chint Alternative Model | Similarities | Differences |
| C10F32D100 | NM1-125S/3300 100A | 3-pole, 100A, 36kA breaking capacity | Chint adopts thermal-magnetic trip unit without display; Schneider adopts electronic trip unit with display |
| NM1-125H/3340 100A | 3-pole, 100A, electronic trip unit | Chint has 50kA breaking capacity with slightly different protection functions |
- Selection and Usage Recommendations
- Selection Key Points
Select protection curves according to load types: for motor loads, it is recommended to set short-time delay to 5-6×Iu
Breaking capacity should be greater than the expected short-circuit current of the system
Consider future expansion; rated current should be slightly higher than the actual load current
- Installation Precautions
Ensure the mounting surface is flat and the tightening torque meets requirements (screw torque 25N·m)
Corresponding cable lugs must be used for terminal connections to avoid heating caused by poor contact
Leave sufficient heat dissipation space around and avoid close installation with heat-generating components
- Maintenance Recommendations
Regular inspection (at least once a year): appearance, tightness status, flexibility of operating mechanism
Check contact condition after short-circuit tripping and replace if necessary
Clean with dry compressed air to avoid moisture and dust accumulation
VII. Troubleshooting Guide
