What this contactor is and where it fits
The Siemens 3RT1016-1AP02-ZW96 is a SIRIUS power contactor in the compact S00 frame size, designed for switching motor loads in control panels and industrial machinery. Its 45 mm width and screw-and-snap-on mounting onto 35 mm DIN rail per DIN EN 50022 mean it slots directly into a standard panel layout without extra adapters.
Key ratings and what they mean for your motor circuit
The headline motor ratings are 4.5 kW at 500 V and 5.5 kW at 690 V — these are the AC-3 duty figures that govern switching of standard squirrel-cage induction motors. For reversing or inching duty (AC-4), the contactor is rated 8.5 A at 400 V, which is the figure you size for plugging or jogging cycles where the contacts break full load current. Coordination is defined: Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination (lower let-through for reduced contact damage) requires a 20 A gL/gG fuse. This lets the panel builder select the right upstream protection without guesswork. The screw-type terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors, with AWG equivalents of 2x (20 to 16), 2x (18 to 14), and 1x 12. That covers the typical motor-circuit wire sizes for this frame.
DIN rail integration and environmental limits
The 45 x 57.5 x 72 mm envelope (width, height, depth) and side-by-side mounting capability mean you can pack multiple contactors on a single rail segment. Front and terminal protection is IP20 — finger-safe for panel interiors, but not rated for washdown or outdoor exposure. Operating temperature range is -25 to +60 °C, with a pollution degree of 3 (conductive pollution, typical for industrial enclosures). Maximum operating altitude is 2 000 m without derating.
