The AC-3e rating covers the same duty for energy-efficient motors with slightly different switching characteristics. The 400 V AC coil pulls 30 VA inrush, then holds at 4.5 VA — common for a panel with 400 V line-to-line control transformers. Mechanical durability is 10 million cycles, with electrical durability at 1.3 million cycles under the AC-3 load at 440 V. That's a solid baseline for a machine that cycles a few times per minute; if your application runs faster than 3600 cycles per hour, the contactor is not rated for that duty. The minimum switching capability is 5 mA at 17 V for the signaling circuit — this matters if you're using the auxiliary contact to switch a PLC input with low wetting current. Below that threshold, the contact may not reliably close the circuit.
The 45 mm width (three 15 mm modules) fits standard enclosure layouts. IP2X finger protection from the front, so it's safe for open-panel installations where operators might reach in.
Carries EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1 — covers the major global markets for industrial control gear. Also listed for use in IEC 60335 appliance standards, which is relevant if the contactor is inside a piece of HVAC or refrigeration equipment. UL 94 V-1 flame rating on the housing.
