Fastens by screw or snaps onto 35 mm or 75 mm standard mounting rail. Dimensions are 139 mm deep, 70 mm wide, and 148 mm high — the S3 footprint fits a standard 70 mm DIN-rail pitch, leaving room for auxiliary contact blocks on the side.
Switching performance and coil draw
Rated for 800 switching operations per hour under AC-3 duty and 250 per hour under AC-4 — the AC-4 figure is the one to watch for reversing or inching applications where the contactor makes and breaks under load each cycle. Auxiliary contacts are rated for PLC-level reliability at 17 V, 5 mA, meaning they can switch low-energy signals without oxidation issues.
Shock resistance tested at 10.6 g for 5 ms and 6.2 g for 10 ms sine pulse on AC. The listed short-circuit coordination with type 1 requires a 200 A gL/gG NH fuse (3NA series) — this keeps let-through energy low enough that the contactor remains functional after a fault.
