Schneider Electric LB1LC03M22 Thermal Magnetic Protection Module

Schneider Electric LB1LC03M22 Thermal-Magnetic Protection Module delivers adjustable thermal overload and magnetic short-circuit protection for Telemecanique INTEGRAL 32 self-protected motor starters. This 3-pole device provides tuned protection in industrial motor control systems, with a thermal overload setting adjustable from 16 to 25 A and a magnetic trip range of 150 to 300 A, while class 10 thermal protection ensures predictable response. Rated up to 690 VAC and classified under AC-43, it offers a breaking capacity of 15 kA at 220–690 VAC and supports motor power ranges of 5.5 kW (220–240 VAC) to 18.5 kW (600–690 VAC). Protection types include thermal overload, magnetic short-circuit, and phase imbalance protection, making it compatible with Telemecanique INTEGRAL 32 LB1LC series starters. The module adheres to IEC 60947-4 Type 2 and NF C 63-650 standards and weighs approximately 0.40 kg. Typical applications include motor control centers, conveyors, pumps, compressors, packaging machines, HVAC systems, and other industrial control panels where reliable overload protection and machine control are essential. Common replacements feature the Schneider Electric LB1LC03M22 and other industry options such as Siemens SIRIUS 3RV2 and Allen-Bradley Bulletin 140M, useful for repair, replacement, retrofit, or automation maintenance.
