DOUBLE POWER SUPPLYWITH AUTOMATIC SWITCHING
The motorised changeover switches automatically manage
changeover under load between two single-phase or three-phase
power supplies, or manually for emergency operations.
These transfer switching (TSE) devices are suitable for low volt-
age systems with interruption of the supply to the load during
transfer.
