Motor Starter Configuration Solution – Schneider Electric CA3-USBCB-01 | TeSys U Series
Where This Product Is Used
The Schneider Electric CA3-USBCB-01 is the dedicated USB-to-serial data transfer cable engineered for TeSys U motor starters (LUCA, LUCB, LUCC, LUCD, LUCE, LUCF, LUCM multifunction control units). It bridges a standard PC USB port to the RJ45 communication port on TeSys U control units, enabling engineers and commissioning technicians to upload, download, and archive motor protection parameters without manual DIP-switch adjustment.
- OEM production lines requiring repeatable motor protection setups across multiple starters
- Panel builders pre-configuring TeSys U units before cabinet delivery
- Maintenance teams performing predictive diagnostics and parameter backup on installed starters
- System integrators commissioning conveyor, pump, fan, and compressor drives in process plants
- MRO departments replacing failed control units and restoring saved parameter profiles

Application-Specific FAQ
Q: Is CA3-USBCB-01 compatible with TeSys D or TeSys K starters?
A: No. This cable is designed exclusively for the TeSys U series control units. TeSys D and TeSys K use different communication interfaces.
Q: Which software do I need to use with this cable?
A: Schneider Electric’s SoMove (successor to PowerSuite) is the recommended free configuration tool. Download it from the Schneider Electric software portal.
Q: Do I need to install a driver?
A: Yes. A USB-to-serial driver (typically CP210x or similar) is required. It is included with SoMove installation or available from the chip manufacturer’s website.
Q: Can I use this cable to monitor live motor data?
A: Yes. SoMove supports real-time monitoring of current, thermal state, and trip history when connected via CA3-USBCB-01.
Q: Is this cable suitable for ATEX/hazardous area use?
A: No. The CA3-USBCB-01 is a standard industrial accessory not rated for hazardous area classification. Disconnect power before connecting in any environment.
