Schneider Electric LB1-LB03P08 Thermal-Magnetic Protection Module

Schneider Electric's LB1-LB03P08 Thermal-Magnetic Protection Module delivers precise motor protection for INTEGRAL 18 self-protected starters, combining adjustable thermal overload with magnetic short-circuit protection for 3-pole systems. The thermal setting ranges 2.5–4.0 A, with a magnetic trip fixed at 15 × the maximum thermal current, and it provides Class 10 ambient-compensated protection with a rated operational voltage up to 690 VAC. This module carries a 42 kA at 480 VAC breaking capacity and weighs about 0.25 kg, designed for industrial motor control applications in MCCs, conveyors, pumps, compressors, packaging machines, HVAC, and other automation panels, compatible with Telemecanique INTEGRAL 18 self-protected starters (LD1LB and LD-series). Standards include IEC 947-4-1 Type 2 coordinated protection and UL.
