- Standard Control Unit (LUCA) + Standard Base (LUBxx): Basic motor protection with thermal-magnetic protection and standard control
- Advanced Control Unit (LUCC/LUCD/LUCM) + Advanced Base (LUBxx0): Premium protection with diagnostics, comunicazione, and extended functions
- Control unit current range ≤ base rated current: per esempio., LUCA32BL (8–32 A) may only be used with LUB32 (32 UN) or LUB38 (38 UN), not LUB12 (12 UN)
- Control voltage is independent of main voltage: Control unit powered via terminals A1/A2 on the base, typically 24 VDC/AC, 48–72 V AC/DC, or 110–240 V AC/DC
- Note applicative
- Montaggio: Control unit plugs directly into power base and locks with a clip; no additional tools required
- Protezione: Basic protection including Class 10 sovraccarico, cortocircuito (13 × Ir max), phase imbalance, perdita di fase, and earth fault (equipment protection)
- Comunicazione: Supports Modbus (with optional communication module) for remote monitoring and diagnostics
- Ambiente: Temperatura operativa -25 °C ~ +70 °C, suitable for most industrial environments
The combination of TeSys Ultra standard control units (LUCA series) and power bases (LUB series) provides a flexible and reliable solution for motor starting and protection, covering three-phase motors from 0.75 kW to 18.5 kW. Selection should be based on motor rated current, control voltage, and protection requirements to ensure safe and stable operation.
