The S00 frame is the smallest in the SIRIUS contactor family, sized for motor loads up to 5.5 kW at 690 V and 4.5 kW at 500 V. That puts it in the light-to-medium motor switching class — pumps, fans, small conveyors.
At 45 mm wide, three of these fit side-by-side in a 150 mm enclosure section with side-by-side mounting permitted. Wire termination accepts 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) — the screw terminals handle up to 4 mm² per clamp, so you can daisy-chain two motor leads or parallel control wires without a separate terminal block. Rated operating current at AC-12 (resistive load) is 10 A maximum. For motor reversing duty (AC-4 at 400 V), the contactor is rated 8.5 A — that's the figure that governs frequent plugging or jogging applications, not the higher resistive rating. The auxiliary contact block carries 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC — the DC switching capability drops sharply with voltage, so inductive DC loads (brake coils, solenoid valves) need verification against the DC-13 curve.
The ZW96 suffix indicates a special variant (customer-specific code), not a standard off-the-shelf 3RT1016. Verify that the ZW96 modification matches your BOM requirement before committing the line — the base electrical ratings are identical to the standard 3RT1016-1AP05, but the special code may carry packaging, labeling, or testing differences.
