Its headline rating is 45 kW at 500 V under AC-3 duty — that's the standard motor-switching category per IEC 60947-4-1, so it directly drives a 45 kW induction motor on a 500 V line without derating. The coil operates on 50 Hz at 230 V rated value, with a pickup range of 0.8 to 1.1 times rated voltage — meaning it pulls in reliably even if the line dips to 184 V.
Mounting and termination
The S3 frame measures 146 mm high, 70 mm wide, and 201 mm deep — check your enclosure depth before committing the BOM line. Main circuit terminals are screw-type, accepting 2x (10 to 50 mm²) stranded or 2x (2.5 to 16 mm²) solid/stranded. Auxiliary terminals handle 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, up to 4 mm² max.
Maximum switching rates are 1 000 cycles/hour at AC-3, 900 at AC-1, 400 at AC-2, and 300 at AC-4 — the AC-4 rate is lower because each cycle stresses the contacts harder. Shock resistance is 10.6 g for 5 ms AC and 6.2 g for 10 ms AC; DC dropout time is 14 to 20 ms, arcing time 10 to 15 ms.
