Why Choose the ABB T7V 1000 PR232/P LSI 1000A Circuit Breaker?
The ABB 1SDA062859R1, designated T7V 1000 PR232/P LSI In=1000A 4p F, is a high-performance four-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. As part of the established ABB Tmax T7 series, it combines a rated current of 1000 A with a PR232/P LSI electronic trip unit for reliable and adjustable overcurrent protection.
The T7V version is engineered for installations requiring very high short-circuit interruption performance. Its PR232/P LSI electronic trip unit provides long-time, short-time and instantaneous protection functions, enabling the breaker to protect electrical circuits against overload and short-circuit conditions while supporting effective protection coordination within industrial distribution networks.
With a four-pole configuration, 1000 A rated current and fixed installation format, the 1SDA062859R1 is well suited to three-phase and neutral distribution systems. It is designed for use in main switchboards, industrial power distribution panels, commercial installations and infrastructure where dependable high-current circuit protection is required.
