Why Choose the ABB T6L 630 1SDA060257R1 Moulded-Case Circuit Breaker?
The ABB 1SDA060257R1 is a high-performance Tmax T6L 630 three-pole moulded-case circuit breaker (MCCB) designed for protection of 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 an electronic PR221DS-I solid-state trip unit and the high short-circuit performance of the T6L platform.
The breaker incorporates an ABB PR221DS-I electronic trip unit, providing current-based protection for demanding distribution applications. Its electronic release offers an overload current setting range of 252–630 A, allowing the protection level to be coordinated with the requirements of the connected circuit while retaining the accuracy and repeatability associated with solid-state protection technology.
The 1SDA060257R1 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 this breaker particularly suitable for switchboards and distribution systems where high prospective fault currents can occur.
