People Electric · Moulded Case Circuit Breaker
Product overview
People Electric RDM8HU is a three-pole moulded-case circuit-breaker series for higher-voltage AC distribution systems. Five frame sizes cover the stated rated-current combinations. M and H breaking levels have separate Icu/Ics ratings at AC800V, AC1000V and AC1140V.

| Insulation / impulse withstand | Ui 1500V; Uimp 12kV |
| Release configuration | Thermal-magnetic distribution protection; confirm complete release and accessory code |
| Reference ambient / altitude | 40°C; altitude ≤2,000m; −5 to +40°C normal conditions |
| Installation | Vertical or horizontal; front or rear connection subject to the ordered construction. Confirm dimensions with the required arc covers and terminals. |
| Optional shunt-release supplies | DC24V, AC230V or AC400V; specify accessory code |
Select the actual operating voltage before checking breaking capacity. Rated current and frame are paired; settings and accessory codes are confirmed separately. Motor-protection duty requires its specified release configuration. Mounting approval must use the exact manufacturer drawing with the required terminal covers and clearances.
Typical applications
- AC distribution at 800V, 1000V or 1140V, subject to coordination with the stated fault-current ratings.
Specify your enquiry
For a focused quotation, include:
- Frame/rated current, M/H level, actual AC voltage, frequency and prospective fault current.
- Distribution or motor duty, trip specification, auxiliary supplies and operating mechanism.
- Front/rear connection, terminal covers, mounting drawing, quantity and destination.
