Why Choose the ABB T8V 2000 PR331/P-LSIG 1SDA065770R1 Circuit Breaker?

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.

PR331/P-LSIG Protection for High-Current Distribution

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.

Typical Applications

  • Main low-voltage power distribution switchboards.
  • High-current three-phase industrial distribution systems.
  • Applications requiring electronic ground-fault protection.
  • Transformer secondary distribution systems.
  • Industrial main incomers and distribution feeders.
  • Manufacturing and process-industry electrical systems.
  • Infrastructure and large commercial power distribution.
  • OEM switchgear and high-capacity electrical distribution assemblies.
