Why Choose the ABB T7L 1000 PR231/P LS/I 1SDA062818R1 Circuit Breaker?
The ABB 1SDA062818R1 is a high-performance SACE Tmax T7L 1000 moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. This configuration combines a 1000 A rated current, three-pole construction and the ABB PR231/P LS/I electronic trip unit for coordinated overload and short-circuit protection.
As part of the ABB SACE Tmax T7 series, the T7L 1000 provides high fault-interruption capability for industrial and commercial electrical installations. The L performance level is engineered for systems with substantial prospective short-circuit currents, making this breaker suitable for main distribution, feeder protection and other high-current applications.
The 1SDA062818R1 is supplied as a three-pole fixed circuit breaker. Its PR231/P LS/I solid-state release combines long-time overload, short-time short-circuit and instantaneous short-circuit protection, providing a comprehensive protection package for high-current low-voltage distribution circuits.

Electronic LS/I Protection for High-Current Distribution
The ABB SACE Tmax T7 platform is engineered for high-current low-voltage installations where dependable circuit protection and interruption of substantial fault currents are required. The T7L 1000 combines the T7 frame with ABB's L performance level, providing a robust solution for demanding switchboards and power distribution assemblies.
The PR231/P LS/I electronic trip unit provides three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection allows controlled response to short-circuit conditions for improved system coordination, and instantaneous protection provides rapid interruption when severe fault currents occur.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and feeder protection in electrical switchboards.
- High-current three-phase distribution circuits.
- Manufacturing and process-industry electrical systems.
- Commercial and infrastructure distribution assemblies.
- Plant and machinery power distribution.
- Fixed switchgear requiring electronic LS/I protection.
