1SDA060583R1 ABB T6L 1000 PR222DS/P-LSIG 1000 A 4P MCCB

Why Choose the ABB T6L 1000 PR222DS/P-LSIG 4P 1SDA060583R1 Circuit Breaker?

The ABB T6L 1000 PR222DS/P-LSIG 1SDA060583R1 is a high-performance four-pole SACE Tmax T6L moulded case circuit breaker rated at 1000 A. Supplied in a fixed configuration with front terminals, it is designed for demanding low-voltage power distribution applications requiring high breaking capacity and comprehensive electronic protection.

At 400–415 V AC, the T6L performance level provides a rated ultimate short-circuit breaking capacity of 100 kA. This makes the breaker particularly suitable for industrial and infrastructure installations where high prospective fault currents require robust interruption capability.

The integrated PR222DS/P-LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. With a rated current of 1000 A and adjustable protection functions, the 1SDA060583R1 provides a flexible protection solution for critical feeders, distribution boards and other high-current electrical circuits.

Advanced LSIG Protection for High-Current Power Distribution

The PR222DS/P-LSIG trip unit gives the ABB T6L 1000 a comprehensive electronic protection package. Long-time protection responds to sustained overloads, short-time protection provides adjustable response to high fault currents where selective coordination is required, and instantaneous protection provides rapid tripping under severe short-circuit conditions. The G function adds ground-fault protection capability to the LSIG protection package.

Combined with the T6L breaker's 100 kA Icu at 400–415 V AC, these electronic protection functions make the 1SDA060583R1 suitable for demanding distribution networks where both high fault-current interruption and adjustable protection characteristics are important. The fixed four-pole design and front connections also provide a practical arrangement for integration into industrial switchboards.

Typical Applications

• Industrial low-voltage main distribution boards.
• High-current feeder protection.
• Manufacturing and process plant electrical distribution.
• Commercial and infrastructure switchboards.
• Four-pole three-phase distribution systems.
