The ABB 1SDA060321R1 is a high-performance Tmax T6L 630 three-pole moulded-case circuit breaker (MCCB) designed for demanding low-voltage AC power distribution applications operating at voltages up to 1000 V AC. As part of the ABB Tmax T4–T8 range, it combines a rated uninterrupted current of 630 A with the PR222DS/P-LSI electronic trip unit and the high-voltage capability of the T6L platform.
The PR222DS/P-LSI electronic trip unit provides long-time, short-time and instantaneous protection functions. This LSI protection arrangement protects electrical circuits against sustained overloads and short-circuit faults while providing adjustable electronic settings that support effective protection coordination within industrial and commercial distribution systems.
The 1SDA060321R1 is supplied as a fixed, three-pole circuit breaker with front terminals. At 1000 V AC, the T6L 630 provides a rated ultimate short-circuit breaking capacity of 12 kA and a rated service short-circuit breaking capacity of 6 kA, making it a purpose-designed solution for high-voltage AC distribution systems requiring reliable ABB electronic circuit protection.
Electronic moulded-case circuit breakers monitor circuit current and initiate tripping when configured protection thresholds are exceeded. The PR222DS/P-LSI release provides long-time protection against sustained overloads together with short-time and instantaneous functions for short-circuit protection, allowing effective coordination between protective devices within a distribution system.
The ABB T6L 630 configuration used in the 1SDA060321R1 is specifically designed for applications operating at up to 1000 V AC. Its 630 A current rating, adjustable LSI electronic protection and 12 kA Icu at 1000 V AC make it suitable for specialised industrial power distribution installations requiring reliable protection at elevated AC voltages.
