ABB 1SCA108530R1001 Change-Over Switch - DNV Certificate

Make-before-break operation ensures a brief overlap (I+II) where both poles are closed during source transfer, with an overlap time limited to about 20 ms. This design minimizes arcing, reduces switching wear, and lowers the risk of momentary outages in critical sections of the panel. Four poles deliver a 200 A main circuit, enabling a compact footprint for high-power switchgear across 380 to 415 V, 500 V, and 690 V systems while maintaining a 1000 V insulation voltage. The result is improved panel reliability and safer transitions between sources, supporting streamlined wiring and smaller enclosure requirements in automation cabinets. Base mounting and screw terminals simplify installation while preserving robust electrical connections; a tightening torque of 15 to 22 N·m ensures consistent clamping. The included black handle and shaft reduce field wiring complexities and speed up commissioning, especially in tight control room environments. Front IP20 protection provides dependable operation in controlled environments, while the fourth pole configuration on the right side enables synchronized switching and easier interlocking schemes in multi-source applications. Compliance and traceability are built in through CE declarations, DNV certification, RoHS and REACH conformity, and SCIP references, making this switch suitable for regulated projects and procurement programs. In terms of lifecycle economics, the transfer switch reduces downtime, extends switchgear life, and supports predictive maintenance programs through documented performance parameters and readily available data sheets.
