ABB 1SDA064875R1 Moulded Case Breaker - UL 489, 4P 1200A

Four-pole construction delivers ready-made high-current protection for large distribution circuits. This architecture reduces the risk of unfused cross-coupling and simplifies busbar connections, cutting wiring errors during installation. Application: ideal for subpanels and main feeders in industrial plants where 4P protection and front-access terminals speed assembly and service. Release PR232/P-LSI delivers precise, reliable tripping performance with state-of-the-art release logic. This improves fault-clearance speed and minimizes arc energy in fault conditions, protecting both equipment and personnel. In motor circuits, the combination of PR232/P-LSI and S-type short-circuit performance delivers consistent protection across a range of load profiles. Regulatory readiness is a core strength. The device carries UL 489 and CE declarations, and ABB Sace RoHS/REACH compliance keeps you aligned with global procurement standards. This reduces qualification delays for multinational projects and supports consolidated supplier qualifications for panel builders and EPCs. Durability and efficiency matter in long-term operation. Mechanical durability reaches 10000 cycles at a standard 60 cycles per hour, supporting frequent switching in maintenance-heavy environments. The unit also reports 47 W power loss per pole, enabling more accurate heat and energy budgeting in large switchboards and contributing to lower operating costs over time. Electrical ratings and compatibility further simplify design-in. Rated insulation voltage is 1000 V, rated operational voltage 630 V AC, and rated impulse withstand voltage is 8 kV, with fixed front-terminal configuration compatible with common MCCB mounting schemes. This makes it suitable for 630 V class networks and high-impedance protections in modern industrial plants.
