ABB 1SDA123634R1 Moulded Case Circuit Breaker - IEC 60947-2
Part Number: 1SDA123634R1
Quick Summary
ABB 1SDA123634R1 Moulded Case Circuit Breaker is designed to protect DC power systems in industrial automation, data centers, and manufacturing lines. This 4-pole XT6N device delivers reliable protection for 750 V DC bus applications with a robust 630 A rating and up to 25 kA short-circuit capability when configured in series. Operators seek long-term reliability and rapid fault isolation; this MCCB addresses those needs with 20,000 mechanical cycles and a low power loss profile. In addition to IEC 60947-2 compliance, it aligns with RoHS and REACH, and ABB’s EcoSolutions program supports end-of-life planning and responsible disposal. Built for panel builders and system integrators, it enables straightforward installation in fixed-circuit-breaker configurations while delivering lifecycle cost savings.
