Why Choose the ABB TruONE OXA160U3S3QB Automatic Transfer Switch?
The ABB TruONE OXA160U3S3QB is a 160 A 4-pole automatic transfer switch designed for dependable automatic transfer between two power sources. Supplied under ABB order code 1SCA153293R1001, it combines the switching mechanism and controller within ABB's integrated TruONE ATS platform.
This model uses a standard switched-neutral 4-pole configuration with open-transition I-II operation. Unlike overlapping-neutral variants, the neutral pole is switched as part of the normal transfer sequence, making the OXA160U3S3QB suitable for applications requiring full 4-pole source switching.
The OXA160U3S3QB incorporates a Level 3 controller with LCD interface and a wide 200–480 V AC voltage range. Its bottom-entry source arrangement places Source 1 and Source 2 connections at the bottom and the load connections at the top, supporting practical integration into compatible switchboard layouts.
Key Advantages
- 160 A UL and IEC rated current for commercial and industrial automatic transfer applications.
- Integrated TruONE design combines the transfer switch and controller in one purpose-built unit.
- 4-pole switched-neutral configuration provides complete switching of phase and neutral conductors.
- Open-transition I-II operation for controlled transfer between two power sources.
- Level 3 LCD controller provides advanced ATS monitoring, configuration and control.
- Wide 200–480 V AC voltage range reduces the need for multiple voltage-specific ATS variants.
- Bottom-entry source connections with load connections at the top.
- Designed for reliable critical, standby and alternative-source power systems.

Integrated 4-Pole Automatic Power Transfer
ABB TruONE integrates the automatic transfer switching mechanism and controller within one purpose-built assembly, reducing the external wiring and individual connection points associated with conventional ATS installations. The OXA160U3S3QB manages transfer between two sources using open-transition I-II operation while providing local configuration and monitoring through its Level 3 LCD controller.
The 4-pole switched-neutral configuration switches the neutral conductor together with the three phase conductors during source transfer. Combined with its 160 A rating, wide voltage capability and bottom-entry source connections, the OXA160U3S3QB provides a compact solution for automatic standby and critical-power installations.
Typical Applications
- Mains-to-generator automatic transfer systems.
- Commercial building standby power systems.
- Industrial control and distribution switchboards.
- Critical manufacturing and process installations.
- Data and communications infrastructure.
- Healthcare and essential-services electrical systems.
- 4-pole systems requiring switched-neutral source transfer.
- Switchboards requiring bottom-entry source and top load connections.
