Why Choose the ABB T8L 3200 PR331/P-LSIG 1SDA065740R1 Circuit Breaker?

The ABB T8L 3200 PR331/P-LSIG 1SDA065740R1 is a high-current four-pole moulded-case circuit breaker (MCCB) from the ABB SACE Tmax T8 range, designed for demanding industrial power distribution applications. It combines a 3200 A rated uninterrupted current with the PR331/P-LSIG electronic trip unit for comprehensive protection of major electrical distribution circuits.

The integrated PR331/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection. This LSIG arrangement enables the breaker to respond to overloads, different levels of short-circuit current and qualifying earth faults, making it particularly suitable for high-current systems where comprehensive electronic protection and coordination are required.

The 1SDA065740R1 is a fixed four-pole breaker equipped with vertical rear terminals and bolt-type main-circuit connections. With a rated voltage of 690 V, adjustable overload protection from 1280–3200 A and the robust T8L platform, it is well suited to main switchboards, large industrial feeders and high-capacity power distribution assemblies.

Advanced PR331/P-LSIG Protection for 3200 A Distribution

The PR331/P-LSIG electronic trip unit provides four principal protection functions for high-current distribution systems. Long-time protection responds to sustained overload conditions, short-time protection enables a controlled response to high fault currents, instantaneous protection provides rapid interruption of severe short circuits, and ground-fault protection adds protection against qualifying faults to earth.

The adjustable protection ranges allow the T8L 3200 to be coordinated with the characteristics of the electrical installation and other protective devices. Combined with its 3200 A rating, four-pole construction and vertical rear connections, the 1SDA065740R1 provides a powerful protection solution for main distribution boards and other high-capacity electrical systems.

Typical Applications

  • Main low-voltage power distribution switchboards.
  • High-current industrial distribution systems.
  • Three-phase four-wire power distribution circuits.
  • Applications requiring electronic ground-fault protection.
  • Transformer secondary distribution systems.
  • Industrial main incomers and high-current feeders.
  • Manufacturing, processing and infrastructure installations.
  • OEM switchgear and high-capacity electrical distribution assemblies.
