OT160G30 ABB 3-Pole Switch Disconnector

Why Choose the ABB OT160G30 Switch Disconnector?

The ABB OT160G30 is a three-pole switch disconnector designed for reliable manual switching and electrical isolation in industrial and commercial low-voltage systems. Part of ABB's compact OT160G range, it supports both IEC and UL/CSA applications and provides robust non-fusible isolation for distribution, machinery and control installations.

The OT160G30 is a front-operated, base-mounted device equipped with protected clamp terminals. Under IEC ratings it provides 160 A AC-22A and AC-23A performance up to 690 V, while its North American rating is 100 A at 600 V under UL 98, with a 125 A UL/CSA ampere rating also specified for the product.

This version is supplied without an operating handle and shaft, allowing the required operating accessories to be selected separately according to the enclosure and installation arrangement. Its compact dimensions and three-pole construction make it a practical choice for high-performance electrical isolation where installation space is important.

Compact Multi-Standard Switching and Isolation

Switch disconnectors provide controlled manual switching together with electrical isolation, allowing equipment and circuits to be disconnected from their supply for maintenance, servicing and operational requirements. The ABB OT160G30 combines compact construction with ratings suited to both IEC and North American electrical installations.

With 160 A AC-23A performance up to 690 V under IEC ratings, a 100 A UL 98 rating at 600 V and protected clamp terminals, the OT160G30 provides a versatile solution for three-phase isolation. Supplying the switch without a handle or shaft also allows its operating arrangement to be configured to suit the individual enclosure.
