Why Choose the ABB T7L 1000 PR332/P LSIG 1000A Circuit Breaker?
The ABB 1SDA062831R1, designated T7L 1000 PR332/P LSIG In=1000A 4p F F M, 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 and a stored-energy operating mechanism.
The T7L version provides high short-circuit interruption performance, with a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC. Its PR332/P LSIG solid-state trip unit provides adjustable long-time, short-time, instantaneous and earth-fault protection, enabling effective protection coordination and selectivity across sophisticated electrical distribution networks.
With its four-pole configuration, fixed installation, front terminals and motorisable stored-energy mechanism, the 1SDA062831R1 is well suited to main distribution boards, industrial switchboards and infrastructure power systems. The breaker supports an operational voltage of up to 690 V AC and provides adjustable protection characteristics for high-current three-phase and neutral distribution circuits.
