What it is and what it does
The Siemens 3RT1017-1AP62 is a SIRIUS power contactor in the compact S00 frame size, designed for switching motor loads in control panels. It mounts via screw or snap-on onto a 35 mm DIN rail per EN 50022, fitting into a 45 mm wide slot with a 57.5 mm height and 72 mm depth — the S00 footprint that panel builders know for high-density layouts. Rated for AC-2 duty at 5.5 kW at 400 V, this contactor handles wound-rotor motor starts and other moderate-inductive loads. For heavy inrush applications like reversing or plugging, the AC-4 rating is 8.5 A at 400 V — the figure that governs real motor-switching life under frequent starts. Operating ambient temperature spans -25 to +60 °C, and the unit is rated for pollution degree 3 environments — typical for industrial enclosures where conductive dust or condensation may be present.
Terminals, wiring, and coordination
Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid/stranded conductors. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. This covers most motor-circuit wiring sizes up to 4 mm² without needing terminal adapters. For Type 2 coordination (no damage to the contactor under short circuit), the required upstream fuse is gL/gG 20 A. Type 1 coordination (contactor may need replacement after fault) allows a 35 A gL/gG fuse. These values guide the MCCB or fuse selection in the feeder circuit. Auxiliary contact ratings span the control voltage range: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC — enough for pilot-duty control circuits across common AC and DC supplies.
Mounting and clearances
Side-by-side mounting is permitted, needing only 6 mm clearance at the side. Front protection is IP20 — finger-safe terminals for the control panel environment. The contactor is rated for operation up to 2,000 m altitude without derating. Mechanical endurance is rated at 30,000,000 operating cycles — a figure that reflects the S00 frame's mechanical life under no-load or light-load switching, not the electrical life under full motor current.
Lifecycle and sourcing
The part carries the SIRIUS brand and is part of the broad S00 contactor family. Sourcing is straightforward: quoted to order against an RFQ, with typical availability through industrial automation distributors. No last-time-buy or phase-out notice is in effect.
