ABB OT16F3C 3-pole 16 A manual change-over switch with open transition operation for low-voltage electrical panels, switchboards and machinery applications.
£75.43
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.
Manual change-over switches are used to transfer electrical loads between two sources while providing safe isolation during the switching process. They are commonly used where controlled manual source selection is required in distribution panels, control systems and machinery applications.
The ABB OT16F3C provides robust switching performance in a compact form factor, making it well suited to panel builders and electrical engineers working with low-voltage systems. Its modular accessory compatibility allows the switch to be adapted with suitable handles and shafts for front-panel operation.
