Schneider has marked the LC1E1801N5WB as obsolete. No official successor order code appears in the lifecycle record. For a line-down or BOM-fill situation, the part is sourced through independent channels against an RFQ — expect to provide a quantity and target delivery window for a firm quote. No last-time-buy window is documented here.
Protective treatment TH per IEC 60068-2-30 (damp heat, cyclic) qualifies it for tropical or non-conditioned environments.
