ABB circuit breaker with residual current release
- Brand: ABB
- Model: T3N 250 + RC223 4p
- Type: Molded case circuit breaker (MCCB) with residual current release (Type B, 4-pole)
- All Tech Specs:
- Material: Thermoplastic/insulated enclosure (T3N); thermoplastic or polycarbonate housing (RC223) for durability and arc resistance
- Poles: 4 (RC223 requires 4-pole configuration; T3N available in 3P or 4P, 4P used here)
- Rated Current: 250A (T3N, adjustable via TMD thermomagnetic release from 250-2500A)
- Rated Voltage: 690V AC (T3N, Ue maximum); 400V AC (RC223, nominal operating)
- Breaking Capacity: Up to 36kA at 415V AC (Icu, T3N); up to 50kA at 400V AC
- Sensitivity Threshold (RC223): 30mA, 300mA, 3000mA (selectable for residual current detection)
- Type (RC223): B (detects AC, pulsating DC, and smooth DC residual currents; complies with IEC/EN 60947-2)
- Frequency Sensitivity (RC223): Selectable maximum threshold (400 Hz, 700 Hz, 1000 Hz) for industrial fault frequencies
- Release Type (T3N): Thermomagnetic (TMD R, thermal for overload, magnetic for short-circuit; adjustable trip settings)
- Frequency: 50/60 Hz (both units)
- Insulation Voltage: 800V (T3N, Ui)
- Impulse Withstand Voltage: 8kV (T3N, Uimp)
- Response Time (RC223): Instantaneous trip for residual faults above threshold
- Protection: Overload and short-circuit (T3N); residual current protection against indirect/direct contacts (RC223)
- Connection: Screw terminals (T3N: front terminals; RC223: integrated with T4 breaker system)
- Mounting: Fixed installation (T3N with RC223; plug-in optional for T3N)
- Operating Temperature Range: -25°C to +70°C (-13°F to +158°F) for both
- Protection Rating: IP20 (standard; IP40 or higher with accessories)
- Standards: IEC/EN 60947-2 (both); suitable for industrial and commercial low-voltage systems
- Certification: CE marked; RoHS compliant; UL listed options available
- Features: Compact design for space-saving; RC223 requires no external power; LED indicators on RC223 for status; suitable for 19-inch racks (no); easy maintenance with modular integration
