Product details

SIRIUS S00 power contactor — 3RT1016-2AP02

The Siemens SIRIUS 3RT1016-2AP02 is a size S00 power contactor rated for motor switching at 4 kW at 400 V AC-3. The 24 VDC coil pulls in reliably across the 0.8 to 1.1 x Us range at 50/60 Hz. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded — no screw torque to verify, which speeds panel wiring.

For reversing or plugging duty (AC-4), the contactor is rated 8.5 A at 400 V, which is the figure to use when the load cycles direction under full load. The S00 frame (45 mm wide, 60 mm tall, 73 mm deep) snaps onto 35 mm DIN rail per EN 50022. Side-by-side mounting is permitted with 6 mm spacing at the side, which keeps the panel fill factor tight.

Type 1 coordination allows a 35 A fuse.

Frequently asked questions

What is the closest functional alternative to the 3RT1016-2AP02?

The 3RT1017-1AP01 is a higher-rated S00 contactor (7 kW at 400 V AC-3) with the same 24 VDC coil and spring-loaded terminals. It is a direct mechanical and electrical swap in the same DIN footprint — no rewiring needed — but carries a higher motor rating if your load requires it.

What compliance documentation is available for this contactor?

The SIRIUS series carries CE marking for the European market and is designed to meet IEC/EN 60947-4-1. RoHS and REACH declarations are standard from Siemens for current-production parts. UL and CSA listings are typical for the SIRIUS line, though the specific file number is not in this record.

Will the 3RT1016-2AP02 drop into a panel specified for the 3RT1017-1AP01?

Yes. Both are size S00 with the same 45 mm width, 35 mm DIN-rail mounting, and spring-loaded terminals. The 3RT1016-2AP02 is a lower current rating (4 kW vs 7 kW at 400 V AC-3), so it fits the same physical space and wiring scheme.
