Quick Summary
ABB 1SCA108486R1001 Change-over switch is a 3-pole manual selector ideal for seamless transfer between power sources in industrial control panels. In practice, unreliable handovers can cause unplanned outages; this unit mitigates that risk with a make-before-break closed-transition that minimizes downtime. It carries CE conformity and a DNV certificate, plus front-face protection rated at IP20, supporting safe operation in demanding environments. Designed for high availability in critical processes, ABB’s durable design helps reduce maintenance cycles and extend service life. Compatible with standard industrial control architectures, it offers a reliable, scalable solution for switchgear in medium- and high-energy applications.
Product Information
Extended Description
1SCA108486R1001 ABB: 160, 3 pole manual change-over switch with phase barriers 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.

FAQs
The switch is rated for 380–415 V across its AC-23A/AC-33B categories with a main circuit insulation voltage of 1000 V, making it suitable for typical industrial distribution panels and motor control centers in this voltage range. It supports 160 A ratings per pole with appropriate wiring and securing torque.
Closed-transition means the two poles swap between positions I and II without an open circuit, with a brief overlap (minimum about 20 ms) where both contacts are closed. This reduces transient interruptions and arc exposure, improving reliability in critical power transfer scenarios.
Yes, the device features front IP20 protection, and is designed for base mounting with screw terminals. Installation is straightforward in standard switchgear cabinets, with a recommended tightening torque of 15–22 N·m per terminal to ensure secure, compliant connections.
This model includes a CE Declaration of Conformity and a DNV certificate, with RoHS/REACH compliance implied through ABB's environmental declarations. These certifications help meet regulatory requirements for industrial, marine, and energy sectors and simplify supplier qualification audits.
Key ratings include 160 A per pole, 1000 V rated operational voltage, 12 kV impulse withstand, and 8 kA short-time withstand current for 1 s. These specs support longer service intervals, lower maintenance costs, and reduced risk of downtime in continuous-operation facilities.
