Key Technical Equivalence Notes
- Domestic Brand Replacements (Direct Drop-in)
Delixi CDC19S-32/11: Fully compatible with CJ19-3211, same mounting dimensions, terminal layout, and electrical specifications
Tengen TGCC1-32/11: Enhanced version with better thermal performance, designed to replace CJ19 series directly
People R19-32/11: Cost-effective alternative with identical functionality
- International Brand Considerations
ABB UA30-30-11: Preferred choice with 1NO+1NC auxiliary contacts, rated at 30A (close enough to 32A for most applications)
Schneider LC1D32KUE: Specifically designed for capacitor switching with built-in current-limiting resistors, ensure to select the “K” ряд
Siemens 3RT2027: Requires external surge protection module for proper capacitor switching, as standard models lack built-in current-limiting resistors
- Critical Compatibility Factors
| Factor | Requirement | Why It Matters |
| Utilization Category | AC-6b (capacitor switching) | Standard AC-3 contactors will fail prematurely with capacitor inrush currents |
| Текущий рейтинг | 32А (or 30A for ABB) | Must match capacitor bank current (typically 20kvar at 400V) |
| Вспомогательные контакты | 1НО+1НЗ | Essential for interlocking and status feedback in compensation systems |
| Mounting Type | Screw-fixed (not DIN rail for CJ19) | Ensure panel cutouts match (standard 4-hole mounting) |
| Напряжение катушки | AC220V/380V (matching control circuit) | Incorrect voltage will damage the coil or prevent operation |
Application Recommendations
- For Reactive Power Compensation Systems:
Prefer domestic brands (Вкусный, Tengen, People) for direct compatibility and cost-effectiveness
For European systems, ABB UA30-30-11 is the most equivalent international model
- When Replacing Existing CJ19-3211:
Verify auxiliary contact configuration (1НО+1НЗ) before purchasing
Ensure new contactor has built-in current-limiting resistors (critical for capacitor protection)
Match coil voltage (AC220V/380V) with existing control circuit
- Installation Notes:
All equivalent models use the same screw-fixed mounting (M4/M5 bolts, torque 2.5~3.5N·m)
Main circuit wiring requires 4mm² copper cables, control circuit uses 1.5mm² cables
Maintain proper spacing (10cm) for heat dissipation, separate main and control circuits to avoid interference
