ABB 1SCA104816R1001 ot16f3c 16amp change-over switch

Why Choose the ABB OT16F3C Manual Change-Over Switch?

The ABB OT16F3C is a compact and reliable 3-pole manual change-over switch designed for safe source transfer and switching in low-voltage electrical installations. As part of the proven ABB OT Series, it provides dependable manual change-over control for industrial panels, machinery, switchboards and power distribution applications.

This switch features an open transition change-over operation, making it suitable for manually transferring loads between two supplies where the circuits must be disconnected before reconnecting to the alternate source. Its front-operated construction, compact footprint and protected clamp terminals make it practical for professional panel building and OEM electrical equipment.

With a 16 A operational rating, 3-pole configuration and 750 V AC rated insulation voltage, the ABB OT16F3C is ideal for small power transfer circuits, control panels, machinery isolation and manual supply selection. The handle and shaft are ordered separately, allowing the switch to be configured for different enclosure layouts.
