It's a current-production part, so no lifecycle scramble; this is what you spec into a new panel or drop in as a line-down spare for an existing S00 footprint.
Motor duty and coordination — the real selection numbers
For AC-4 (plugging/reversing/inching) at 400 V, the rated operational current is 8.5 A. These are the numbers that govern contact life, not the 10 A AC-12 resistive rating. Type 1 coordination requires a 35 A gL/gG fuse; type 2 coordination needs a 20 A gL/gG fuse. If you're coordinating with a motor starter or overload relay, the 20 A type 2 limit is the one that keeps the contactor re-usable after a fault.
Both main and auxiliary/control circuits use screw-type terminals. The main contacts accept 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or max 2x (0.75...4 mm²) solid or stranded — same ranges for the auxiliary contacts. AWG equivalents are 2x (20...16), 2x (18...14), and 1x 12. The 72 mm depth, 45 mm width, and 57.5 mm height fit a shallow backpanel.
Storage temperature exceeds that range — the handling limit, not the running limit. RoHS compliance date is 01.07.2006, so it meets the original EU RoHS directive. Electrical life depends on the switching category and current; at AC-2 5.5 kW you'll get a fraction of that, but still well into the millions for most conveyor or pump cycling rates.
