LUCA05BL 製品仕様

LUCA05BL is a standard control unit of Schneider’s TeSys U series, suitable for three-phase motors. It features an adjustable rated current of 1.25–5A, a control voltage of 24V DC, and a Class 10 thermal overload rating. Equipped with protection against overload, 短絡, 位相損失, phase interruption, そして地絡, it is designed for direct-on-line starting control of motors below 1.5kW (400V).

製品のポジショニング & アプリケーション

– As a standard control unit of the TeSys U series, it combines with compatible power bases (例えば, LUB05) to form a direct-on-line starter, providing basic control and protection for three-phase motors.

アプリケーションシナリオ: Light to medium-load working conditions such as pumps, ファン, コンプレッサー, and small conveyor lines, suitable for industries including textile, 製紙, chemical engineering, and food & 飲み物.

Differentiation from Series Peers: Unlike LUCB (advanced type with alarm/test functions) and LUCC (communication type), LUCA only provides basic protection with a lower cost.

選択 & 交換

Compatible Bases: LUB05, LUB05BL, 等. The base must match the rated current of the control unit.

置換参照: Equivalent models from Chint NJR2 series and ABB MS116 series. しかし, interface and protection logic differences exist; it is necessary to verify installation dimensions and control circuit parameters.

インストール & メンテナンスガイドライン

1. Install via DIN rail or screw mounting; modular plug-and-play design enables quick replacement.
2. The control circuit requires an external 24V DC power supply. Set Ir (1.25-5A) on the main circuit according to the motor’s rated current.
3. Manual reset is required after a fault. Ground fault protection is only for equipment and does not replace personal safety protection.
4. 使用温度範囲: -25～+60℃. Avoid dusty, 湿気が多い, and corrosive environments; regularly check wiring and terminal tightness.

調達 & 供給

Common Channels: Schneider authorized distributors, industrial e-commerce platforms. Reference price: approximately €60–100 (tax included). In-stock delivery typically takes 2–5 working days.

互換性のあるアクセサリ: Can be paired with LUFDA local alarm module and LULC remote signal module to expand status monitoring functions.

Detailed Comparison Between Schneider TeSys U Series LUCA05BL and LUCB05BL

主な違いの概要

1. 機能の違い: The core advantages of LUCB05BL are overload pre-alarm + 故障警報 + manual test, which can detect motor overload trends in advance to avoid downtime losses. 対照的に, LUCA05BL only provides post-fault protection with no pre-alarm capability.
2. 拡張機能: LUCB05BL can be connected to external alarm lights, PLC, or remote monitoring modules to adapt to automated systems; LUCA05BL has no expansion interface and only meets basic control needs.
3. 料金 & 費用対効果: LUCA05BL is suitable for cost-sensitive scenarios with simple working conditions; LUCB05BL is ideal for industrial scenarios requiring high reliability. Although it has a higher price, it can reduce fault troubleshooting time and maintenance costs.

選択の推奨事項

– If end customers only require “basic motor protection against damage”, prioritize LUCA05BL for higher cost-effectiveness.

– If customers operate in scenarios such as automated factories and production lines that require fault pre-alarm and remote monitoring, recommend LUCB05BL to improve equipment operation rate.

Cross-Brand Selection Comparison Table: Schneider LUCA05BL/LUCB05BL vs. Chint NJR2-5 vs. ABB MS116-5

Key Selection Conclusions

1. Chint for Cost Priority: NJR2-5 has the lowest price, suitable for domestic low-end equipment supporting, but lacks short circuit and ground fault protection and needs to be used with additional circuit breakers.
2. ABB for Integrated Control: MS116-5 is an integrated protection circuit breaker with built-in closing/opening functions, requiring no base matching, suitable for scenarios with high integration requirements.
3. Schneider LUCB for Automated Scenarios: Equipped with alarm and test functions, it can be connected to PLCs for remote monitoring, reducing fault troubleshooting time, ideal for high-end production lines.
4. Schneider LUCA for Basic Protection: Balanced functions with a lower price than LUCB and ABB, suitable for overseas small and medium-sized customers without monitoring needs.

Export Adaptation Tips (For Markets Such as Algeria)

– Both Schneider and ABB products are certified by IEC and CE, directly meeting the import certification requirements of African countries such as Algeria.

– Chint NJR2-5 requires additional local access documents such as SASO certification. Some channels can handle the certification on behalf of customers, with a cost increase of approximately 10%–15%.
