Schneider Electric LB1-LC03M04 Protection Module

Schneider Electric's LB1-LC03M04 Protection Module (LB1LC03M04) is a three-pole thermal-magnetic protection accessory designed for direct mounting on compatible INTEGRAL self-protected motor starters, delivering adjustable overload and magnetic short‑circuit protection in industrial motor control systems. Used in MCCs, conveyors, pumps, compressors, packaging machines, HVAC, and other industrial control panels, this LB1LC03M04 provides an adjustable thermal current range of 0.4–0.63 A and a magnetic trip setting from 6 to 12 times the maximum thermal current (approximately 3.8–7.6 A), with a rated operational voltage up to 690 VAC and a 42 kA breaking capacity at 480 VAC when paired with a compatible INTEGRAL starter. Part of the INTEGRAL 32 (LB1LC) series, it is compatible with LD1LC030, LD4LC030, and LD5LC130 devices and carries recognized standards including IEC 947-6-2, UL, CSA, VDE, ASTA, DEMKO, NEMKO, and SEMKO.
