ABB 1SDA063004R1 Moulded Case Circuit Breaker - PR331 LSIG

Four-pole construction at 1600 A rating delivers robust protection across phase-to-phase and phase-to-ground faults. The four-pole design with front terminals and a lever operating mechanism ensures reliable tripping and straightforward maintenance, reducing downtime during inspections and replacements in high-energy distribution panels. Release PR331/P LSIG provides a precise, industry-standard trip curve, improving selective coordination in multi-breaker installations and lowering the risk of unnecessary outages. Application: used in Tmax T7 protective schemes in manufacturing lines and transformer stations. High fault current capability ensures reliable protection for feeders and busbars, with Ics up to 85 kA and Icu up to 85 kA depending on voltage, and Icw of 20 kA for 1 s, enhancing safety in 690 V systems. RoHS, REACH, and SCIP compliance mitigate regulatory risk and simplify end-of-life handling. Durable mechanics and limited maintenance requirements reduce lifecycle costs, while the compact footprint and fixed-front connections support straightforward retrofits into existing switchgear. Electrical durability of 2000 cycles and mechanical durability of 10000 cycles at 60 cycles per hour translate to longer service life and lower maintenance frequency. Weight at 17.737 kg, dimensions of 280 mm width x 268 mm height x 154 mm depth, and front-terminal accessibility streamline installation and service in industrial environments.
