OT160G04K ABB 160 A 4-Pole Switch-Disconnector with Direct Handle

Why Choose the ABB OT160G04K 160 A 4-Pole Switch-Disconnector?

The ABB OT160G04K is a compact, high-performance 160 A 4-pole switch-disconnector designed for dependable load switching and electrical isolation in industrial low-voltage systems. Part of the ABB OT160G range, it provides four-pole switching for applications requiring simultaneous disconnection of three phase conductors and a neutral conductor.

This K-version is supplied with an ABB YAST1 direct-mounted non-lockable handle for convenient local operation. The switch features an end-mounted operating mechanism, protected screw terminals and base or DIN-rail mounting capability, providing a practical compact solution for machinery panels, distribution boards and industrial switchgear.

The OT160G04K is rated at 160 A for AC-22A and AC-23A duty at 690 V AC. It also carries North American ratings of 100 A UL 98 Listed and 125 A UL 98 Recognized at 600 V, making it suitable for equipment designed around IEC or UL/CSA requirements.
