Why Choose the ABB T8V 2000 PR332/P-LSIG 1SDA065773R1 Circuit Breaker?
The ABB T8V 2000 PR332/P-LSIG 1SDA065773R1 is a high-current three-pole moulded-case circuit breaker (MCCB) from the ABB SACE Tmax T8 range. Designed for demanding low-voltage power distribution, it combines a 2000 A rated uninterrupted current with the advanced PR332/P-LSIG electronic trip unit.
The PR332/P-LSIG provides long-time, short-time, instantaneous and ground-fault protection. This LSIG protection package enables the breaker to respond to sustained overloads, short-circuit conditions and qualifying earth faults, providing comprehensive electronic protection for high-capacity industrial distribution systems.
The 1SDA065773R1 is a three-pole fixed breaker with front terminals and a rated voltage of 690 V. Its adjustable electronic protection and T8V performance platform make it particularly suitable for main switchboards, transformer secondary distribution, industrial incomers and other installations where high current and substantial prospective fault levels must be managed.

Advanced PR332/P-LSIG Electronic Protection
The PR332/P-LSIG trip unit gives the T8V 2000 four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection provides an adjustable response to high fault currents, instantaneous protection enables rapid interruption of severe short circuits, and ground-fault protection extends the protection package to qualifying faults to earth.
For the 1SDA065773R1, overload protection can be adjusted across 800–2000 A, while short-time protection has an adjustment range of 1200–20000 A and instantaneous protection can be adjusted across 3000–24000 A. These adjustable characteristics make the breaker well suited to coordinated high-current distribution systems where protection settings must be matched to the installation.
Typical Applications
- Main low-voltage power distribution switchboards.
- High-current three-phase industrial distribution systems.
- Industrial main incomers and high-capacity feeders.
- Transformer secondary distribution systems.
- Applications requiring electronic ground-fault protection.
- Manufacturing and process-industry electrical systems.
- Infrastructure and large commercial power distribution.
- OEM switchgear and high-capacity electrical distribution assemblies.
