ELECTRICAL HAZARD
● De-energize panel before installation (Verify with CAT III 1000V multimeter)
● Use GE-approved torque wrench (TL-20K) for terminal connections
| Parameter | Requirement |
|---|---|
| Mounting Position | Vertical (±5° tolerance) |
| Busbar Connection | 35mm² min copper, tin-plated |
| Torque Values | Main lugs: 50 Nm ±10% |
| Ambient Temperature | -25°C to +60°C (derate 1%/°C >40°C) |
Step-by-Step Guidance
- Mechanical Mounting
- Align with DIN rail (EN 60715) until audible “click”
- Secure end stoppers (P/N: ES-CK12)
- Electrical Connections
[Power Terminals] L1/L2/L3: Phase sequence marking → Follow IEC 60445 [Control Wiring] A1/A2: 24-230V AC/DC (Use 0.75-2.5mm² flex cable) - Pre-Operation Check
- Measure contact resistance: ≤50μΩ (DLRO test)
- Verify trip unit settings: Iⁿ=125A, Ir=0.8 (Factory default)
