SIRIUS 3RT1016-1AV61 — 3-pole power contactor, size S00
The Siemens SIRIUS 3RT1016-1AV61 is a size S00 power contactor with three normally open main contacts, designed for screw and snap-on mounting onto a 35 mm standard mounting rail per DIN EN 50022. Its 24 VDC coil draws a rated operational current of 10 A, making it suitable for switching motor loads in control panels where a compact 45 mm wide footprint is needed. The AC-4 rating at 400 V is 8.5 A, which governs the contactor's capability for reversing or inching duty — the most demanding switching category for AC motor loads. For standard AC-2 motor switching at 400 V, it is rated for 4 kW, and at 500 V it handles 4.5 kW, with a 690 V rating of 5.5 kW.
Termination and wiring
Main circuit terminals are screw-type, accepting solid conductors from 2x (0.5... 1.5 mm²) up to a maximum of 2x (0.75... 4 mm²), or AWG equivalents 2x (20... 16) through 1x 12. The front of the contactor carries an IP20 protection rating, as do the terminals, so it is suited for installation inside an enclosure where no washdown or dust ingress is expected. Side-by-side mounting is permitted with a clearance of 6 mm at the side, which helps panel builders pack multiple contactors tightly on the DIN rail.
Coordination and protection
For Type 2 coordination (no damage to the contactor after a short circuit), the required upstream fuse is gL/gG rated at 20 A. For Type 1 coordination (contactor may need replacement after a fault), a 35 A gL/gG fuse is specified. The contactor is rated for a pollution degree of 3, meaning it can operate in environments with conductive pollution or where dry non-conductive pollution may become conductive due to condensation — typical for industrial control panels. Operating temperature range is -25 to +60 °C during operation, with a maximum altitude of 2 000 m.
Lifecycle and sourcing
For BOM line items or urgent replacements, the 3RT1016-1AV61 is specified into the design and can be sourced to order against an RFQ — confirm fit by matching the 24 VDC coil voltage and the 3-pole, size S00 footprint against your panel layout.
