Siemens 3RT1016-1AM22 — SIRIUS S00 Power Contactor, 24 VDC Coil
The Siemens 3RT1016-1AM22 is a SIRIUS-brand power contactor in the compact S00 frame size, designed for switching motor loads and resistive circuits in industrial control panels. It mounts on a 35 mm DIN rail per DIN EN 50022 with a screw-and-snap-on mechanism, occupying 45 mm of panel width. Rated for a 24 VDC coil, the contactor switches 10 A at 24 V DC, 2 A at 60 V DC, 1 A at 110 V DC, and 0.3 A at 220 V DC — covering the common DC control voltages found in battery-backed and PLC-driven systems. For AC motor duty, it delivers 4 kW at AC-2 400 V and 8.5 A at AC-4 400 V, suiting it for reversing and plugging applications where high electrical wear is expected. Higher-voltage motor ratings reach 4.5 kW at 500 V and 5.5 kW at 690 V, which means this S00 frame handles three-phase motors up to about 5.5 kW on 690 V networks — typical for European 690 V industrial distribution.
Mounting & Integration
The contactor snaps onto a 35 mm DIN rail (EN 50022) and supports side-by-side mounting without derating — a key advantage when packing multiple contactors into a narrow enclosure. Dimensions are 45 mm wide, 57.5 mm high, and 72 mm deep, fitting standard S00 panel layouts. Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded conductors, with AWG equivalents of 2x (20 to 16), 2x (18 to 14), or 1x 12. The front and terminal areas carry IP20 finger protection, safe for use in enclosed panels. Pollution degree 3 rating means it tolerates conductive dust and humidity typical of industrial floors — no special cabinet climate control needed for most factory environments.
Lifecycle & Sourcing
For fuse coordination, type 2 coordination (no damage to the contactor on short circuit) requires a gL/gG fuse rated 20 A; type 1 coordination (contactor may need replacement after fault) allows a 35 A gL/gG fuse. This lets the panel designer balance protection level against fuse size. Mechanical life is rated at 30 million operating cycles typical — a high endurance figure for the S00 class, suited for frequent cycling applications like conveyor indexing or valve actuation.
