Why Choose the ABB T5L630 PR222DS/P-LSIG 630 A 1SDA054423R1 Circuit Breaker?
The ABB 1SDA054423R1 is a high-performance SACE Tmax T5L 630 moulded case circuit breaker (MCCB) designed for protection and isolation in demanding low-voltage power distribution systems. Configured as a fixed three-pole breaker with front terminals, it combines a 630 A rated current with ABB's PR222DS/P-LSIG electronic trip unit.
Part of the established ABB SACE Tmax T5 series, the T5L630 provides comprehensive electronic LSIG protection, covering long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault conditions. This combination supports flexible protection coordination across industrial, commercial and infrastructure distribution networks.
The PR222DS/P-LSIG release provides a 252–630 A long-time overload adjustment range and short-circuit protection adjustable across a 945–5,985 A range. Combined with the high-breaking-performance T5L platform, the 1SDA054423R1 provides robust protection for substantial three-phase feeders and distribution circuits where high prospective fault currents and earth-fault protection must be addressed.
