Schneider Electric LUCA32BL

Specifiche tecniche & Guida all'applicazione

1. Panoramica del prodotto

Schneider LUCA32BL is a standard control unit from the TeSys Ultra series (formerly TeSys U series), a component of three-phase motor starters. It must be used with LUB series power bases (such as LUB32 / LUB38) to form a complete motor starting and protection system. It features thermal-magnetic protection and is suitable for industrial applications requiring basic motor protection including overload, cortocircuito, perdita di fase, phase imbalance, e protezione dai guasti a terra.

TeSys Ultra (formerly TeSys U) Standard Control Unit Range & Power Bases

1. Complete List of Standard Control Units (LUCA Series)

TeSys Ultra standard control units use thermal-magnetic protection and provide overload, cortocircuito, perdita di fase, phase imbalance, e protezione dai guasti a terra. They are only compatible with standard power bases (Serie LUB) and not with advanced bases (LUBxxx0 series). All models are Class 10, 3-palo (3P) three-phase devices.

Convenzione di denominazione dei modelli

LUC: Prefix for TeSys Ultra control units

UN: Unità di controllo standard (Advanced versions: C/D/M)

XX: Current range code (1X = 0.35–1.4 A, 05 = 1.25–5 A, 12 = 3–12 A, 18 = 4.5–18 A, 32 = 8–32 A)

Suffisso: BL = 24 VCC, ES = 48–72 V AC/DC, FU = 110–240 V AC/DC, B = 24 VCA

2. Complete List of Power Bases (LUB Series)

TeSys Ultra power bases are divided into standard bases (nessun suffisso) and advanced bases (suffisso 0), both 3P three-phase, for different control unit types.

2.1 Standard Power Bases (For LUCA Series Standard Control Units)

2.2 Advanced Power Bases (For LUCC / LUCD / LUCM Advanced Control Units)

2.3 Reversing Power Bases (For Reversing Control Units)

3. Key Matching Rules
4. Standard Control Unit (LUCA) + Base standard (LUBxx): Basic motor protection with thermal-magnetic protection and standard control
5. Advanced Control Unit (LUCC/LUCD/LUCM) + Advanced Base (LUBxx0): Premium protection with diagnostics, comunicazione, and extended functions
6. 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)
7. Control voltage is independent of main voltage: Control unit powered via terminals A1/A2 on the base, tipicamente 24 VDC/AC, 48–72 V AC/DC, or 110–240 V AC/DC
8. Note applicative
9. Montaggio: Control unit plugs directly into power base and locks with a clip; no additional tools required
10. Protezione: Basic protection including Class 10 sovraccarico, cortocircuito (13 × Ir max), phase imbalance, perdita di fase, e guasto a terra (equipment protection)
11. Comunicazione: Supporta ModBus (with optional communication module) for remote monitoring and diagnostics
12. Ambiente: Temperatura operativa -25 °C~ +70 °C, adatto per la maggior parte degli ambienti industriali

La combinazione di unità di controllo standard TeSys Ultra (serie LUCA) e basi di potere (Serie LUB) fornisce una soluzione flessibile e affidabile per l'avviamento e la protezione dei motori, covering three-phase motors from 0.75 kW a 18.5 kW. Selection should be based on motor rated current, tensione di controllo, and protection requirements to ensure safe and stable operation.
