The ABB 1SDA054432R1 is a high-performance SACE Tmax T5V 630 moulded case circuit breaker (MCCB) designed for protection and isolation in demanding low-voltage power distribution systems. Configured as a fixed four-pole breaker with front terminals, it combines a 630 A rated current with ABB's PR221DS-LS/I electronic trip unit.
Part of the established ABB SACE Tmax T5 series, the T5V630 provides electronic LS/I protection for overload and short-circuit conditions. Its electronic release offers adjustable thermal protection from 0.4–1 × In and adjustable magnetic protection from 1–10 × In, allowing the breaker to be coordinated with cables, feeders and connected equipment.
The T5V performance level is designed for installations with exceptionally high prospective fault currents, delivering an ultimate short-circuit breaking capacity of 200 kA at 380–415 V AC. The four-pole configuration also provides selectable neutral protection settings of OFF, 50% or 100%, making the 1SDA054432R1 a flexible solution for demanding three-phase four-wire distribution systems.
The ABB SACE Tmax T5V platform is engineered for demanding low-voltage power distribution where substantial current capacity and very high short-circuit interruption performance are required. With a 630 A rated current and 200 kA Icu at 380–415 V AC, the 1SDA054432R1 is particularly suited to high-current feeders and distribution systems with significant prospective fault levels.
Its PR221DS-LS/I electronic trip unit provides adjustable overload and short-circuit protection, while selectable neutral protection adds flexibility for four-wire distribution systems. Together with fixed mounting and front terminals, these characteristics make the breaker suitable for integration into industrial switchboards, commercial distribution panels and infrastructure power systems.
