The LC1E06004M5WBIN: AC-1 is the resistive-load curve — this contactor is not rated for motor starting (AC-3) or inductive switching. The 20 A rating at ≤415 V is the operational current for that duty; the rated breaking capacity is 48 A at 440 V, and the making capacity hits 60 A at 440 V AC per IEC 60947-4-1. Electrical durability is 150,000 cycles under AC-1, with mechanical durability at 10 million cycles — a solid figure for a panel that cycles a few times per hour. The 4 NO pole configuration with no auxiliary contacts means you'll need a separate contactor or relay block for feedback signals. Control circuit screw-clamp terminals accept 1 to 4 mm² flexible with cable end, or up to 6 mm² solid. The 80 mm depth, 45 mm width, and 74 mm height fit standard DIN-rail or plate mounting — no surprises for panel layout.
Protective treatment TH per IEC 60068 means it's tested for tropical humidity — no extra coating needed for damp environments. Active lifecycle status means it's a current catalog item, not a phase-out.
Sourcing and integration
The 12 A gG fuse coordination type 1 at ≤690 V is specified for the power circuit; use that as the upstream protection limit.
