Reliable Protection for High-Current DC Systems
Direct-current networks present demanding interruption requirements because DC does not have the natural periodic current-zero points found in alternating-current systems. Circuit breakers used in these networks therefore require technology specifically engineered for DC fault interruption. ABB's SACE Emax DC platform is designed to provide switching and protection for these specialised power distribution applications.
The PR123/DC electronic release used with the 1SDA064741R1 provides dedicated protection for DC networks. Combined with the E4S/f frame, 2500 A current rating, four-pole arrangement and withdrawable construction, this circuit breaker provides a practical solution for high-current installations requiring dependable protection and maintainable switchgear integration.
