Disconnect switch OT80F3, 80A, 3-pole, without shaft and handle 1SCA105798R1001

Isolator switch – reliable disconnection in your installation

This 3-pole isolator switch OT80F3 from ABB is a robust solution for safely disconnecting electrical circuits. Designed for use in switchboards and as a main isolator, it provides effective isolation and protection of the installation. The lack of a shaft and handle makes it a compact device, easy to install and integrate with existing systems.

Functionality and application

The OT80F3 isolator is widely used in electrical power distribution systems, especially where reliable load disconnection is required. It is ideal as:

• Main isolator in low-voltage switchboards – allows safe disconnection of the entire installation during maintenance or emergency work.
• Repair isolator – allows disconnection of a section of the installation during modernization or repairs.
• Safety system element – provides the ability to quickly and reliably disconnect the power supply in hazardous situations.

The device design allows mounting on DIN rail or directly on the switchboard plate, increasing installation flexibility.
