ABB 1SDA127157R1 Moulded Case CB - IEC 60947-2
Part Number: 1SDA127157R1
Quick Summary
ABB 1SDA127157R1 is a high-performance moulded case circuit breaker designed for DC power distribution in industrial automation. It protects circuits against overloads and short circuits in 750 V DC networks, enabling safer and more reliable panel operation. The XT4N family offers a 4P configuration, 100 A nominal current, and a robust 8 kV impulse withstand, delivering dependable protection in demanding environments. This device is compatible with fixed-circuit-breaker installations and integrated with ABB EcoSolutions for responsible end-of-life handling, including disassembly guidance and recyclability reporting. For procurement and compliance teams, IEC 60947-2 compliance, CE marking, and RoHS declarations simplify documentation and reduce risk, while supporting lower total cost of ownership in DC distribution and renewable-energy applications.

Feature: 4P fixed configuration with 100 A DC rating provides compact, space-saving protection for DC circuits. Business Impact: reduces panel footprint and installation time while delivering predictable protection. Application: ideal for DC distribution boards in industrial automation, motor drives, and battery storage systems. Feature: High short-circuit capability (Ics up to 36 kA, Icu up to 36 kA depending on pole count and voltage) enhances safety margins. Business Impact: minimizes arc energy during faults and improves system resilience. Application: critical protection in data centers, renewable energy interfaces, and heavy-drive applications. Feature: Insulation voltage of 1000 V and operational voltage of 750 V DC provide a wide safety margin. Business Impact: supports compliant design for higher-voltage DC networks and reduces risk of insulation failure. Application: DC busbars and power rails in industrial panels. Feature: Release mechanism TMD with TM type and a Short-Circuit Performance Level of N supports fast, selective tripping. Business Impact: improves coordination with upstream protection and reduces downtime. Application: protective schemes in multi-breaker panels and automation cabinets. Feature: EcoSolutions data, RoHS/REACH compliance, and 56.3% recyclability per EN45555 enable sustainable asset management. Business Impact: lowers environmental footprint, simplifies compliance reporting, and supports corporate sustainability goals. Application: lifecycle planning for panel builders and green-data center initiatives. Feature: Robust installation and compatibility with fixed-circuit-breaker terminals, plus documented end-of-life instructions. Business Impact: reduces commissioning risk and streamlines maintenance planning. Application: OEM panel construction, retrofit projects, and new-build automation equipment.
