One supplier across changeover, protection and distribution
ATSE is the core of the range. Circuit protection, surge protection and assembled switchgear are supplied alongside it so the project interfaces are consistent.
Where power continuity is a design requirement, not a preference
Each application page sets out the loads that need changeover, the interruption each load tolerates, the typical configuration and the related products.
Choose by current, poles and class
The selection matrix maps current rating to the poles, class and typical transfer time. Open the ATSE overview to compare frames, or request a sizing check with your single-line diagram.
| Current Rating | Poles | Class | Typical Transfer Time | Typical Use |
|---|---|---|---|---|
| 100A – 320A | 2P / 3P / 4P | PC / CC | 0.5 s – 3 s | Essential lighting, small plant rooms |
| 400A – 800A | 2P / 3P / 4P | PC / CC | 0.8 s – 5 s | Building main boards, hospitals, data rooms |
| 1000A – 1600A | 3P / 4P | PC / CC | 1 s – 10 s | Hospital mains, data center feeds, risers |
| 2000A – 3200A | 3P / 4P | PC | 1.5 s – 15 s | Utility incomers, large data halls, process plants |
Built around continuity rather than price per unit
The design decisions behind the range are about behaviour under transfer, not about winning on the lowest unit cost.
In-house controller and mechanism
The control logic and mechanical linkage of the ATSE range are developed in house rather than assembled from third-party modules, which keeps behaviour consistent across ratings.
Built around supply continuity
The range is specified around transfer time, restart behaviour and class selection, so the changeover supports continuity rather than simply switching between sources.
Type tested to IEC 60947-6-1
ATSE equipment is tested to IEC 60947-6-1, and type-test evidence is available during procurement review.
Manufacturing in Yueqing since 2003
Production, assembly and routine testing take place in the Yueqing facility, under ISO 9001 and ISO 14001 management systems.

Send a drawing, get a sizing check
Tell us the application, the current rating you are considering and the transfer time you need. We will come back with a class and configuration recommendation.
- Send the single-line diagram and fault level for a sizing check
- Request the series datasheet and IEC 60947-6-1 type-test evidence
- Ask for a changeover assembly quote including control and signalling
