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.","metaTitle":"Siemens 3RT1016-1AS02 SIRIUS Power Contactor, 45mm, AC-4 8.5","metaDescription":"Siemens 3RT1016-1AS02 SIRIUS power contactor, size S00, 45mm wide, AC-4 8.5A at 400V.
