The 110 V 50 Hz coil pulls in reliably across the 0.8 to 1.1 times rated voltage range. Screw-type terminals on the main circuit accept stranded cable up to 2x 25 mm², and solid or ferrule-terminated conductors from 0.5 mm² up to 4 mm² on the auxiliary circuit.
This contactor is not explicitly rated for AC-3 in the evidence, but the AC-2 rating of 22 kW at 400 V confirms it is sized for slip-ring or wound-rotor motor applications. Maximum switching frequency varies by duty: 1000 cycles/hour for AC-1 (resistive loads), 400 for AC-2, 800 for AC-3, and 300 for AC-4 — the AC-4 figure is the limiting one for high-cycle jogging applications.
The S2 frame occupies 55 mm width, 112 mm height, 115 mm depth. Front face is IP20; the terminal area is IP00 — the panel builder must maintain clearance and cover live parts as part of the overall enclosure rating.
Wire termination details
Main circuit screw terminals accept stranded conductors from 2x 0.75 mm² up to 2x 25 mm². Auxiliary circuit terminals handle solid wire from 0.5 mm² to 4 mm² (max 2x 4 mm²).
Substance prohibitance date of 05/01/2012 aligns with RoHS compliance. The contactor carries the SIRIUS brand from Siemens.
