Why Choose the ABB T7L 1000 PR331/P LSIG Moulded Case Circuit Breaker?
The ABB T7L 1000 PR331/P LSIG is a high-performance 3-pole moulded case circuit breaker (MCCB) designed for protection and control of demanding low-voltage power distribution systems. As part of the established ABB Tmax T7 series, it combines a 1000 A rated current with electronic protection and a high short-circuit breaking capacity.
Equipped with the PR331/P LSIG electronic trip unit, the T7L 1000 provides long-time, short-time, instantaneous and earth-fault protection functions. The overload protection setting can be adjusted across 400–1000 A, supporting coordinated protection of cables and distribution equipment in industrial and commercial installations.
With an ultimate short-circuit breaking capacity of 120 kA at 400 V AC, 50 Hz, a rated voltage of 690 V AC and a fixed configuration with front terminals, the T7L 1000 is engineered for switchboards and distribution systems where high fault-current capability and dependable electronic protection are required.

Reliable Circuit Protection for Power Distribution
Moulded case circuit breakers such as the ABB Tmax T7 protect electrical distribution circuits against overload, short-circuit and fault-current conditions. The electronic protection unit monitors circuit current and initiates interruption when configured protection thresholds are exceeded, helping protect cables, switchgear and connected equipment.
The T7L 1000 combines a high current rating and high breaking capacity with LSIG protection, making it particularly suitable for installations with substantial prospective fault currents. Its adjustable PR331/P electronic release enables protection settings to be coordinated with the requirements of the downstream electrical distribution system.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incomer and feeder circuit protection.
- Commercial building power distribution.
- Manufacturing and process-industry electrical systems.
- Power distribution centres and switchgear assemblies.
- High-fault-level three-phase electrical networks.
