Why Choose the ABB T7L 1000 PR331/P LSIG Moulded Case Circuit Breaker?
The ABB T7L 1000 PR331/P LSIG is a high-performance 4-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 advanced electronic protection and high short-circuit breaking capability.
Equipped with the PR331/P LSIG electronic trip unit, the T7L 1000 provides long-time, short-time, instantaneous and earth-fault protection functions. Its adjustable protection settings support effective coordination of cables, switchgear and downstream equipment in industrial and commercial electrical distribution networks.
With an ultimate short-circuit breaking capacity of 120 kA at 380/415 V AC, a rated voltage of 690 V AC and a fixed four-pole configuration with front terminals, the T7L 1000 is engineered for switchboards and power distribution assemblies where high fault-current capability and comprehensive 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 earth-fault conditions. The electronic protection unit monitors circuit current and initiates interruption when configured protection thresholds are exceeded, helping protect cables, switchgear and connected electrical equipment.
The T7L 1000 combines a high current rating and high breaking capacity with adjustable LSIG protection. Its four-pole construction and integrated earth-fault functionality make it particularly suitable for demanding low-voltage distribution systems requiring coordinated protection of phase and neutral conductors.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incomer and feeder circuit protection.
- Four-pole three-phase distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process-industry power systems.
- Power distribution centres and switchgear assemblies.
- High-fault-level electrical networks.
