Product details

At 230 V the rated operational current is 6 A, at 400 V it is 3 A, and at 690 V it drops to 1 A; these are the values that govern real motor sizing, not the maximum voltage alone. Its S00 footprint — 45 mm wide, 57.5 mm tall, 72 mm deep — leaves room for auxiliary contact blocks and side-by-side mounting without derating. The AC coil draws 0.27 W holding power and 0.8 W closing power, which keeps thermal load low in dense panels.

Integration and protection

The front and terminal areas are IP20 protected. For type 2 coordination (no-weld after fault), the required upstream fuse is a gL/gG 20 A NH 3NA; for type 1 coordination (allow weld but no fire), use 35 A. The contactor can accept an auxiliary switch block (product extension auxiliary switch = yes).
