OT160GT03 ABB 160 A 3-Pole Door-Mounted Switch-Disconnector

Why Choose the ABB OT160GT03 160 A 3-Pole Door-Mounted Switch-Disconnector?

The ABB OT160GT03 is a compact 160 A 3-pole switch-disconnector designed for dependable load switching and electrical isolation in industrial low-voltage systems. Part of the ABB OT160G switch-disconnector range, it combines high IEC switching capability with UL/CSA ratings for machinery, switchboards and power distribution applications.

This OT160GT version is specifically designed for door mounting and features a front-operated mechanism with protected clamp terminals. The OT160GT03 is supplied without a handle and shaft, allowing compatible ABB operating accessories to be selected separately to suit the enclosure and installation requirements.

For IEC applications, the OT160GT03 provides 160 A AC-22A and AC-23A operational current at 690 V AC. For North American applications, it is rated at 100 A UL 98 Listed and 125 A UL 98 Recognized at 600 V, making it a versatile solution for equipment designed for international markets.

Reliable Door-Mounted Switching and Isolation

The ABB OT160GT03 provides dependable three-phase switching and isolation with 160 A AC-23A capability at up to 690 V AC. Its AC-23A performance makes it suitable for demanding industrial loads, while the three-pole configuration provides simultaneous switching of all three phase conductors.

Its door-mounted construction is particularly useful where the switching mechanism is to be integrated directly with an electrical enclosure door. Because the OT160GT03 is supplied without a handle and shaft, compatible ABB accessories can be selected separately to suit the required operating arrangement and enclosure design.

Typical Applications

• Industrial machinery main switching and isolation.
• Door-mounted electrical disconnect applications.
• Three-phase motor and inductive-load circuits.
• Industrial switchboards and distribution panels.
• Manufacturing and process equipment.
• OEM machinery requiring IEC and UL/CSA switching solutions.
