Why Choose the ABB T6L 630 1SDA060258R1 Moulded-Case Circuit Breaker?
The ABB 1SDA060258R1 is a high-performance Tmax T6L 630 three-pole moulded-case circuit breaker (MCCB) designed for protection of demanding low-voltage industrial and commercial power distribution systems. As part of the ABB Tmax T4–T8 range, it combines a rated uninterrupted current of 630 A with the advanced PR222DS/P-LSI electronic trip unit and the high short-circuit performance of the T6L platform.
The PR222DS/P-LSI solid-state release provides long-time, short-time and instantaneous protection functions. This LSI protection arrangement enables the breaker to protect circuits against sustained overloads and short-circuit faults while offering adjustable protection settings for effective coordination with downstream equipment and the characteristics of the electrical installation.
The 1SDA060258R1 is supplied as a fixed, three-pole circuit breaker with front terminals and is rated for operation at up to 690 V AC. The T6L performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–415 V AC, making it particularly suitable for switchboards and distribution systems with high prospective fault currents.
