Reliable Circuit Protection for Power Distribution
Moulded case circuit breakers such as the ABB Tmax T7 protect low-voltage electrical distribution circuits against overload and short-circuit conditions. The electronic protection unit monitors circuit current and initiates interruption when configured protection thresholds are exceeded, helping protect conductors, switchgear and connected electrical equipment.
The T7V 1250 combines a high 1250 A current rating with 150 kA breaking capability at 380/415 V AC and adjustable PR232/P LSI protection. Its four-pole construction and fixed front-terminal configuration make it well suited to high-capacity three-phase distribution systems requiring coordinated electronic circuit protection.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incomer and feeder circuit protection.
- High-current four-pole three-phase distribution systems.
- Commercial and infrastructure electrical distribution.
- Manufacturing and process-industry electrical systems.
- Power distribution centres and switchgear assemblies.
- High-fault-level low-voltage electrical networks.
