Why Choose the ABB 1SDA065730R1 T8L 2000 Circuit Breaker?
The ABB 1SDA065730R1 is a high-current SACE Tmax T8L 2000 moulded case circuit breaker (MCCB) designed for demanding industrial power distribution applications. Identified by ABB as T8L 2000 PR331/P LSIG In=2000A 4p F F, it combines a 2000 A current rating, four-pole construction and a PR331/P-LSIG solid-state electronic trip unit.
The PR331/P-LSIG trip unit provides comprehensive electronic protection functions covering long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault protection (G). This combination makes the breaker suitable for installations requiring coordinated protection against multiple electrical fault conditions.
Designed for 690 V AC systems, the 1SDA065730R1 features fixed construction with front terminals and a rated uninterrupted current of 2000 A. Its T8L frame, electronic protection and four-pole configuration make it particularly suitable for high-current industrial switchboards, main distribution systems and three-phase four-wire power networks.

Comprehensive LSIG Protection for High-Current Distribution
High-current power distribution systems require protection that can distinguish between overloads, short-duration fault conditions, severe short circuits and ground faults. The ABB PR331/P-LSIG electronic release combines these functions within the T8L platform, providing long-time, short-time, instantaneous and ground-fault protection for coordinated industrial distribution applications.
The ABB 1SDA065730R1 combines this LSIG protection with a 2000 A four-pole circuit breaker rated for operation at 690 V AC. Fixed mounting and front connections make it well suited to main switchboards, distribution assemblies and other installations requiring a permanently installed high-current protection device.
Typical Applications
- Industrial main power distribution switchboards.
- High-current three-phase four-wire distribution systems.
- Manufacturing and process industry electrical infrastructure.
- Systems requiring electronic ground-fault protection.
- Transformer secondary and main distribution circuits.
- Commercial and industrial low-voltage switchgear assemblies.
