SIRIUS 3RT1016-2AF04 — Power Contactor, Size S00
It mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 50022, and the main current circuit terminates on spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded conductors. This contactor is rated for motor duty at 4.5 kW at 500 V and 5.5 kW at 690 V, with an AC-2 rating of 4 kW at 400 V and an AC-4 rating of 8.5 A at 400 V — the AC-4 figure governs the switching of inching or reversing loads where the contactor makes and breaks the motor current under full load. Pollution degree 3 is declared, meaning the part is suitable for industrial atmospheres with conductive or dry non-conductive pollution.
As a SIRIUS component, full compliance documentation — including RoHS, REACH, and the EU Declaration of Conformity — is available from Siemens. The contactor carries the CE mark and is designed to meet IEC 60947-4-1 for contactors and motor-starters.
Coordination and Auxiliary Contacts
These values are critical for selectivity studies in a distribution board. The contactor carries one normally open instantaneous auxiliary contact rated at 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — sufficient for feedback to a PLC or to seal in a holding circuit.
Physical Integration
Dimensions are 45 mm wide, 60 mm tall, and 114 mm deep — the depth is the dimension behind the panel face when DIN-rail mounted. The spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) or 2x (24 to 14 AWG) conductors. No screw torque specification is needed — the spring cage provides consistent clamping force independent of the installer.
