The ABB T8V 2000 PR331/P-LSIG 1SDA065770R1 is a high-performance three-pole moulded-case circuit breaker (MCCB) from the ABB SACE Tmax T8 range. Designed for demanding industrial power distribution, it combines a 2000 A rated uninterrupted current with the PR331/P-LSIG solid-state electronic trip unit.
The integrated PR331/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection. This LSIG functionality provides comprehensive protection against overloads, short circuits and qualifying earth-fault conditions while offering adjustable protection settings for coordination within large electrical distribution systems.
The 1SDA065770R1 is a fixed three-pole breaker with front terminals and is rated for operation up to 690 V AC. The T8V performance level provides a high breaking capacity, including 130 kA at 380/415 V AC, making this breaker particularly suitable for installations with substantial prospective fault currents.
The PR331/P-LSIG electronic trip unit provides four principal protection functions. Long-time protection responds to sustained overload conditions, short-time protection provides adjustable response to high fault currents, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection provides an additional response to qualifying faults to earth.
Combined with the T8V 2000 breaker platform, these functions provide flexible protection for high-capacity distribution systems. The breaker offers an overload adjustment range of 800–2000 A and a breaking capacity of up to 130 kA at common low-voltage distribution voltages, supporting installations where both high load currents and substantial prospective fault levels must be managed.

The ABB 1SDA065770R1 is a 2000 A three-pole fixed SACE Tmax T8V moulded-case circuit breaker with front terminals and a PR331/P-LSIG electronic trip unit for high-current power distribution.
The PR331/P-LSIG provides long-time, short-time, instantaneous and ground-fault protection, collectively identified as LSIG.
The T8V 2000 has an ultimate short-circuit breaking capacity of 130 kA at 380/415 V AC. Its published Icu values also include 130 kA at 220/230 V AC and 440 V AC, 100 kA at 500 V AC and 80 kA at 690 V AC.
The breaker has a rated uninterrupted current of 2000 A. Its PR331/P-LSIG electronic trip unit provides an adjustable overload setting range of 800–2000 A.
The specification identifies a three-pole fixed circuit breaker with front terminals. This configuration is intended for permanent installation in compatible three-phase switchboards and power distribution assemblies.
ABB SACE Tmax T8 circuit breakers combine high-current switching capability with electronic protection for demanding low-voltage distribution systems, providing configurable overload, short-circuit and ground-fault protection for industrial, infrastructure and main power applications.
