Product details

Siemens SIRIUS 3RT1016-1AK61 — Power Contactor, Size S00, 690 V 5.5 kW

The Siemens SIRIUS 3RT1016-1AK61 is a size S00 power contactor rated for 5.5 kW at 690 V, with an AC-4 current rating of 8.5 A at 400 V — meaning it handles the high-stress reversing or inching duty cycles typical of conveyor drives and hoist controls without derating the main contacts.

Rated Operational Currents and Wire Sizing

The main circuit screw terminals accept solid or stranded conductors: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), or max 2x (0.75... 4 mm²) — which covers the typical control wiring range for a size S00 contactor and avoids the need for ferrule adapters on stranded runs. Auxiliary and control circuit terminals use the same screw-type design, with identical wire ranges, so the same crimp tool and strip length work across all connections.

This lets the panel designer choose between protection level and fuse economy.
