The LC1E0901B6: It complies with EN/IEC 60947-1, -4-1, and -5-1, plus GB/T 14048 equivalents, and passes the glow-wire test at 850 °C per IEC 60695-2-1. That makes it acceptable for equipment meeting IEC 60335 household-application clauses on fire resistance.
The 45 mm width (one standard 45 mm module) and 74 mm height fit a standard control-panel layout without crowding adjacent devices. Depth is 80 mm including the coil terminals — check clearance to the gland plate or enclosure door if panel depth is tight. The contactor is rated IP2X finger-safe on the front, but the terminals need the panel enclosure to provide the full IP rating.
