4LA41100102V1.2 KB2
Schneider Electric TeSys K Series Low-Voltage Motor Protection & Control Module (Model: 4LA41100102V1.2; Variant: KB2)
(Model Naming Interpretation:
- 4LA41100102V1.2: Schneider’s global material and version identifier. “4LA” designates the TeSys K product family (specialized for low-voltage motor control), “41100102” defines the hardware configuration (including adjustable current range and multi-voltage control support), and “V1.2” indicates the 1.2th revision—optimized for overload protection accuracy and EMC performance.
- KB2: Variant code for functional differentiation. “KB” stands for “Integrated Motor Control + Protection” (combining contactor, overload relay, and phase-failure detector), while “2” specifies the rated current range (1.6-2.5A) and compatibility with 0.37-1.1kW motors (at 380V AC), tailored for small-to-medium industrial motor applications.
- Core Positioning: An “all-in-one compact motor management unit” that replaces traditional discrete setups (contactor + thermal overload relay), simplifying wiring, saving cabinet space, and enhancing motor safety in industrial environments.)
2. Product Description
The 4LA41100102V1.2 KB2 is an integrated low-voltage motor protection and control module developed by Schneider Electric for TeSys K series, featuring integrated functionality, space-saving design, industrial-grade durability, and flexible configuration as its core strengths. It is widely used in scenarios such as logistics conveyor motor control, water treatment pump protection, and workshop ventilation fan operation. Its core value lies in resolving pain points of traditional motor control systems—complex wiring (reducing wiring points from 15+ to 8), limited cabinet space (40% smaller footprint), and single-dimensional protection—by integrating multi-layer safety mechanisms and intelligent diagnostics.
