4P fixed design with front terminals simplifies wiring, testing, and service access, reducing panel downtime and enabling faster maintenance cycles in transformer protection and switchgear applications. The 320 A rated current and 690 V AC operating voltage provide robust protection for medium- to high-power loads, improving system reliability and minimizing unplanned outages in data centers, manufacturing lines, and process plants. The PR221DS-LS/I solid-state release delivers precise tripping and fast fault clearance, translating into fewer nuisance trips and safer motor starts in demanding environments. With Ics up to 200 kA and Icu values specified across typical voltages, this MCCB delivers strong short-circuit protection for critical feeders and transformers. Durability figures—7000 electrical cycles and 20000 mechanical cycles—support extended service life, lowering maintenance costs and replacement cycles. The unit’s compact footprint (186 mm x 205 mm x 103.5 mm) and 6.2 kg weight simplify panel integration and logistics, while RoHS and REACH compliance ensure regulatory readiness across regions.
