Why Choose the ABB OT16F4N2 Switch Disconnector?

The ABB OT16F4N2 is a compact and reliable 4-pole switch disconnector designed for safe isolation and switching of low-voltage electrical circuits. As part of the proven ABB OT Series, it provides dependable manual isolation for industrial control panels, machinery, switchboards and power distribution systems.

This switch disconnector features a front-operated, base-mounted design and is also DIN rail mountable, making it well suited to panel building and OEM electrical assemblies. Protected clamp terminals support secure cable connections, while the non-fusible construction provides a straightforward isolation solution for control and distribution applications.

With a 16 A operational current, 4-pole configuration and compact panel-mounted format, the ABB OT16F4N2 is ideal for isolating three-phase circuits where neutral switching is also required. The operating handle and shaft are supplied separately, allowing flexible configuration for different enclosure designs.
