Part Number: 1SCA108518R1001
Quick Summary
ABB 1SCA108518R1001 Change-Over Switch provides fast transfer for 4-pole power circuits in industrial control panels. In critical production lines, even microseconds of OFF-time can trigger alarms, extend downtime, and disrupt process safety. The device carries CE Declaration of Conformity, a DNV certification, RoHS compliance, and CMRT documentation to support global procurement and regulatory adherence. Designed for panel builders and OEMs, it combines reliable isolation with straightforward base mounting, screw-terminal wiring, and a robust black IP20 front with a 4P configuration. This combination translates to predictable performance, easier compliance, and reduced field rework across automated plant environments.
