Siemens SIRIUS 3RT1016-1AP01-ZW95 — Power Contactor, Size S00, 230 V Coil
The Siemens SIRIUS 3RT1016-1AP01-ZW95 is a size S00 power contactor with a 230 V 50/60 Hz coil, rated for switching motor loads up to 4 kW at 400 V in AC-3 duty.
The AC-3 rating of 4 kW at 400 V defines the maximum motor load this contactor can switch under standard starting conditions — that is the figure to match against your motor nameplate, not the AC-1 resistive rating. The coil draws its rated voltage at 230 V 50/60 Hz; the operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz means the coil holds in across a sag down to 184 V at 50 Hz or 195.5 V at 60 Hz, and drops out below that — important for brownout coordination. The mechanical life of 30 million operations is typical for a S00 frame; the electrical life will be lower and depends on the switched current and duty cycle.
The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors; AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12. The contactor stands 57.5 mm tall and 72 mm deep — verify clearance behind the DIN rail for the depth, especially in shallow enclosures.
