Why Choose the ABB T7L1000 PR231/P-LS/I 1000A 4-Pole Circuit Breaker?
The ABB T7L1000 PR231/P-LS/I is a high-performance moulded case circuit breaker (MCCB) designed for reliable 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 for adjustable overload and short-circuit protection.
The PR231/P-LS/I electronic release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. These protection functions allow the breaker to respond effectively to different overcurrent conditions while supporting coordination and selectivity within industrial and commercial electrical distribution systems.
This model is supplied in an authoritative 4-pole fixed configuration. The T7L performance level is engineered for installations requiring substantial short-circuit interruption capability, while its 1000 A rating makes it suitable for main distribution, high-current feeders and other demanding low-voltage applications.
