OT160EV03K ABB 160 A 3-Pole Switch Disconnector with Direct Handle

Why Choose the ABB OT160EV03K 160 A 3-Pole Switch Disconnector?

The ABB OT160EV03K is a 160 A three-pole switch disconnector designed for dependable manual switching and electrical isolation in industrial and commercial low-voltage power distribution systems. Part of the ABB OT switch-disconnector series, it combines compact construction with reliable switching performance for distribution boards, machinery and industrial control assemblies.

This model is front operated and base mounted and is supplied with a black Test-OFF-ON direct-mounted plastic handle and shaft as standard. The direct-handle configuration provides convenient operation at the switch itself, while the handle can be padlocked in the OFF position to support secure electrical isolation during maintenance.

The OT160EV03K has a conventional free-air thermal current of 200 A and operational ratings of 200 A AC-22A and 160 A AC-23A at 400–415 V. With a rated insulation voltage of 1000 V, a 12 kV impulse withstand voltage and robust short-circuit performance, it is engineered for demanding low-voltage switching applications.
