Siemens 3RT1016-1AS02 — SIRIUS Power Contactor, Size S00
Rated for AC-4 duty at 8.5 A and 400 V, this contactor handles the severe switching conditions of plugging or inching motor loads — the high electrical stress of making and breaking locked-rotor current. For less demanding AC-2 service (starting and running slip-ring motors), it carries 4 kW at 400 V. Motor output ratings at 400 V 50 Hz reach 4.5 kW, and at 690 V 60 Hz reach 5.5 kW, covering a range of small-to-medium induction motor applications on pumps, fans, and conveyors.
Mounting and Integration — Panel Fit
Width is 45 mm, height 57.5 mm, depth 72 mm. The S00 frame fits tightly on a DIN rail; side-by-side mounting is permitted, with 6 mm spacing required to the side of adjacent devices for heat dissipation. Screw terminals accept 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or max 2x (0.75...4 mm²) — solid or stranded — and AWG equivalents 2x (20...16), 2x (18...14), 1x 12. The front and terminal faces carry IP20 finger protection.
Coil and Auxiliary Contact Ratings
The contactor's coil operates at 50 Hz (0.8...1.1 x rated voltage) and 60 Hz (0.85...1.1 x rated voltage). Auxiliary contact ratings are 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V — sufficient for pilot duty in most control circuits. Mechanical life is typical 30 million operations. Type 1 coordination (device may need replacement after fault) allows a 35 A fuse.
