Why Choose the ABB T7V 1000 PR331/P LSIG 1000A Circuit Breaker?
The ABB 1SDA062860R1, designated T7V 1000 PR331/P LSIG 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 PR331/P LSIG electronic trip unit for comprehensive and adjustable circuit protection.
The T7V version is engineered for installations requiring very high short-circuit interruption performance. Its PR331/P LSIG electronic trip unit provides long-time, short-time, instantaneous and earth-fault protection functions, enabling the circuit breaker to protect distribution networks against overloads, short circuits and earth faults while supporting coordinated protection throughout the installation.
With a four-pole configuration, 1000 A rated current and fixed installation format, the 1SDA062860R1 is well suited to three-phase and neutral distribution systems. Its robust Tmax T7 construction makes it suitable for main switchboards, industrial power distribution panels, commercial installations and infrastructure applications requiring dependable high-current protection.
