Why Choose the ABB T7V 1000 PR332/P LSIG 1000A Circuit Breaker?
The ABB 1SDA062847R1, designated T7V 1000 PR332/P LSIG In=1000A 4p F 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 proven ABB Tmax T7 series, it combines a rated uninterrupted current of 1000 A with the advanced PR332/P LSIG electronic trip unit for comprehensive circuit protection.
The T7V version provides very high short-circuit interruption performance, with a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. Its PR332/P LSIG electronic trip unit provides adjustable long-time, short-time, instantaneous and earth-fault protection, enabling effective coordination and selective protection across sophisticated electrical distribution networks.
With its four-pole configuration, fixed installation and front terminals, the 1SDA062847R1 is suitable for three-phase and neutral distribution systems in industrial plants, commercial buildings and infrastructure installations. Its combination of a 1000 A current rating and high breaking capacity makes it particularly suitable for main switchboards and distribution circuits with substantial prospective fault currents.
