Why Choose the ABB 1SDA063084R1 T7L 1600 Circuit Breaker?
The ABB 1SDA063084R1 is a high-performance Tmax T7L 1600 moulded case circuit breaker (MCCB) designed for protection and switching of high-current low-voltage electrical distribution systems. Equipped with the advanced PR331/P LSIG electronic trip unit, this four-pole breaker provides adjustable long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection for demanding industrial and commercial installations.
As part of the ABB SACE Tmax T7 series, the T7L 1600 combines a substantial continuous current rating with high fault-breaking performance. Its L performance level provides an ultimate short-circuit breaking capacity of 120 kA at 400 V AC, 50 Hz, while its 1600 A rated uninterrupted current makes it suitable for main distribution boards, high-current feeders and large industrial power systems.
The 1SDA063084R1 is supplied as a fixed four-pole circuit breaker with front terminals and a stored-energy operating mechanism. Rated for 690 V AC, with adjustable overload protection from 640–1600 A and integrated earth-fault protection, it provides flexible and dependable protection for demanding low-voltage distribution installations.
