Why Choose the ABB T7L1000 PR231/P-I 1000A 4-Pole Circuit Breaker?
The ABB T7L1000 PR231/P-I is a high-performance moulded case circuit breaker (MCCB) designed for reliable short-circuit protection and switching in high-current low-voltage power distribution systems. As part of the proven ABB SACE Tmax T7 series, it combines a 1000 A rated current with the PR231/P electronic trip unit and T7L high-breaking-capacity performance.
The PR231/P-I solid-state release provides adjustable instantaneous short-circuit protection, allowing rapid interruption of severe fault currents. This configuration is particularly suitable where overload protection is provided separately or where dedicated instantaneous protection is required as part of a coordinated electrical distribution system.
This model is supplied in a 4-pole fixed configuration with front terminals and a stored-energy operating mechanism. With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 120 kA at 400–415 V AC, the T7L1000 is engineered for demanding industrial and commercial switchboard applications.

High-Performance Short-Circuit Protection
Moulded case circuit breakers such as the ABB Tmax T7 provide dependable switching, isolation and fault protection for low-voltage electrical distribution systems. The high interruption capability of the T7L frame enables severe prospective short-circuit currents to be safely interrupted before they cause extensive damage to conductors and connected equipment.
The PR231/P-I electronic release is configured specifically for instantaneous short-circuit protection. Its adjustable operating threshold allows the protection characteristics to be coordinated with the electrical installation, while the four-pole construction enables simultaneous switching of all three phases and the neutral conductor.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-main power distribution systems.
- High-current feeder protection.
- Manufacturing and process facilities.
- Commercial and infrastructure electrical installations.
- Distribution systems requiring high short-circuit interruption capability.
