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, and earth fault protection.

Con il suo design compatto, protezione completa, e ampia compatibilità, it is an ideal choice for starting and protecting three-phase motors in industrial automation, especially for cost-sensitive applications requiring basic protection.

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, and earth fault protection. 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: Standard control unit (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) + Standard Base (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, and earth fault (equipment protection)
11. Comunicazione: Supports Modbus (with optional communication module) for remote monitoring and diagnostics
12. Ambiente: Temperatura operativa -25 °C~ +70 °C, suitable for most industrial environments

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.
