ABB 1SDA054410R1 Moulded Case Circuit Breaker - PR222DS/P-LSI CE

4P fixed-front terminal design simplifies wiring and service, reducing commissioning time and field wiring errors. In ABB Tmax T5, this layout supports clean panel installations and safer maintenance access, enabling quicker fault finding and component replacement in control cabinets and switchgear. PR222DS/P-LSI solid-state release provides precise tripping characteristics and reduced mechanical wear over the life of the breaker. This improves protection accuracy for peak loads and minimizes nuisance trips, translating into higher uptime for critical lines and easier spare-part planning. With a rated current of 630 A and a rated operational voltage of 690 V AC, this MCCB accommodates large motors and power distribution feeders while maintaining a healthy safety margin. The 1000 V insulation rating supports reliable operation in mixed voltage environments, simplifying integration with upstream transformers and distribution panels. Short-circuit resilience is demonstrated by a service short-circuit breaking capacity up to 85 kA at lower voltages and 25 kA at 690 V, complemented by an 8 kV test impulse withstand. This combination delivers dependable fault clearance and protects both equipment and personnel in demanding industrial settings. Certified and traceable, the device carries IEC standards with CE declarations and GL certification, alongside REACH and RoHS compliance data. The packaging and environmental information help procurement teams meet regulatory requirements while reducing compliance risk across multi-site deployments. The robust mechanical durability (20,000 cycles) and electrical durability (5,000 cycles) also support predictable maintenance planning.
