People Electric · Air Circuit Breaker
Product overview
People Electric RDW8HU intelligent air circuit breakers distribute power and provide coordinated overload, short-circuit and ground-fault protection in AC distribution systems. The main-circuit voltage rating is separate from the auxiliary control supply. Protection functions, sensing connections and settings must be matched to the selected controller and system design.
Technical selection summary
| Manufacturer / series | Original People Electric RDW8HU |
|---|---|
| Main circuit | AC800V, AC1000V or AC1140V; 50/60Hz |
| Rated insulation / impulse withstand voltage | Ui 1250V; Uimp 12kV |
| Poles | 3P or 4P |
| 2500A frame current options | 630, 800, 1000, 1250, 1600, 2000, 2500A |
| 4000A frame current options | 800, 1000, 1250, 1600, 2000, 2500, 2900, 3200, 3600, 4000A |
| 6300A frame current options | 4000, 5000, 6300A |
| 2500A frame Icu / Ics / Icw (1s) | At AC800V: 60kA; AC1000V: 55kA; AC1140V: 50kA. The source lists the same values for these three ratings. |
| 4000A frame Icu / Ics / Icw (1s) | At AC800V: 75kA; AC1000V: 60kA; AC1140V: 60kA. |
| 6300A frame Icu / Ics / Icw (1s) | At AC800V: 85kA; AC1000V: 66kA; AC1140V: 66kA. |
| Controller versions | M: standard, digital display; R: enhanced, LCD; H: advanced, LCD with communication |
| Installation / main-terminal connection | Fixed or draw-out; horizontal or vertical connections as selected and shown in the applicable frame drawing |
| Auxiliary control supplies offered | AC230V, AC400V, DC110V or DC220V; confirm the voltage of each installed accessory |
| Control-circuit isolation | Do not connect high main-circuit voltage directly to the auxiliary control circuit. R/H voltage measurement requires the specified voltage-conversion module. |
| Opening / closing time | 25–30ms without added delay; closing ≤70ms |
| Standard configuration | Shunt release, closing electromagnet, motor operation, four groups of changeover contacts, door frame and phase partitions, as listed in the selection guide |
| Optional accessories | Undervoltage release, interlocks, locks, sensing transformers and communication accessories require an explicit confirmed specification |
| Standard stated | GB/T 14048.2 |
Frame current and rated load current are different selections. The current buttons are restricted to the selected frame. Icu, Ics and 1-second Icw depend on both frame and main-circuit voltage; do not apply the highest rating to every version. The auxiliary control-voltage selection does not change the main-circuit rating. Specify required protective functions, sensors, settings and accessory supplies in the enquiry; no optional undervoltage or communication accessory is assumed included.
Typical applications
- AC800–1140V industrial distribution networks requiring selective circuit protection.
- Main or feeder protection using a correctly coordinated intelligent controller, voltage measurement module and switchboard installation.
