Quick Summary
ABB 1SCA108504R1001 Change-Over Switch provides four-pole, make-before-break switching for reliable high-power panel applications. In practice, engineers contend with transfer arc, limited enclosure space, and the need to avoid outages during switching. This device delivers a minimum 20 ms overlap between positions I and II, along with a robust 160 A rated current and 12 kV impulse withstand. Certifications matter for compliance and field acceptance, and this model carries CE conformity, RoHS compliance, and a DNV certificate. With base mounting, screw terminals, and a compact footprint, it minimizes panel depth while supporting dependable control and protection schemes.
Product Information
Extended Description
1SCA108504R1001 ABB: 160, 4 pole manual change-over switch operating on closed transition principle. i.e. make-before-break operation without OFF-position. Between positions I and II, there is a position I+II where both switches are closed simultaneously. The overlapping time when both contacts are closed is minimum 20 ms. Operating angle of the handle is 90°. Including a black plastic IP65 I - I+II - II pistol type handle (see the table below), shaft and bolt set for the cable connection. Handle not padlockable and no door interlocking.
