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 T7L 1250 combines a high 1250 A current rating and 120 kA breaking capacity at 380/415 V AC with PR332/P LSI Rc electronic protection. Its four-pole construction and residual-current functionality make it particularly suitable for demanding three-phase distribution systems requiring comprehensive overload, short-circuit and residual-current 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.
- Installations requiring residual-current protection.
