ABB 1SDA123531R1 Moulded Case CB - IEC 60947-2

Feature → 4-pole fixed circuit-breaker configuration delivers robust DC protection across all poles, maximizing safety and limiting fault propagation. Business impact → This reduces downtime and simplifies coordination with upstream power supplies in DC distribution cabinets used in automation cells. Application → Ideal for 4P DC distribution panels in manufacturing lines and data centers. Feature → Rated current of 20 A with a rated insulation voltage of 1000 V and rated operational voltage of 500 V DC. Business impact → Enables safe operation across typical industrial DC buses while maintaining high fault isolation. Application → Suitable for compact DC power distribution modules in control cabinets. Feature → High short-circuit resilience with Ics/Icu of 50 kA (at 250 V DC for 2 poles in series; 500 V DC for 3 poles in series). Business impact → Protects critical loads from catastrophic faults and enables upstream protection coordination. Application → Essential in critical automation zones and PLC/drive supply rooms. Feature → Low power loss per pole (1.62 W). Business impact → Improves energy efficiency and reduces heat load in enclosure spaces. Application → Beneficial for energy-conscious data centers and high-density control panels. Feature → Mechanical durability rated at 25,000 cycles and a rated-uninterrupted current of 160 A. Business impact → Extends service life, reduces maintenance cycles, and supports stable long-term operation. Application → Reliable choice for continuous operation in manufacturing lines and process control. Feature → Environmental and compliance footprint with EPD, RoHS, REACH, WEEE classification, and 55.7% recyclability. Business impact → Supports sustainability reporting and regulatory compliance while simplifying end-of-life planning. Application → Aligns with corporate green initiatives and supplier ESG requirements.
