The Siemens SIRIUS 3RT1016-2AP62 is a size S00 power contactor rated for motor switching at 5.5 kW at 690 V and 8.5 A in AC-4 duty at 400 V — the AC-4 figure governs reversing and plugging applications where the contactor makes and breaks stalled-rotor current, so that 8.5 A is the number to size against for frequent jogging or inching cycles. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded, matching the panel builder's standard ferrule set without lug crimping. Mounts via screw and snap-on onto 35 mm DIN rail per EN 50022, occupying 45 mm width — a standard 4-module footprint that drops into existing SIRIUS panel layouts.
Coordination and Protection
For Type 2 coordination (no damage to the contactor under short circuit), the required upstream fuse is gL/gG 20 A; for Type 1 coordination (contactor may need replacement after fault), the fuse is gL/gG 35 A. These values let the panel designer size the branch protection without derating guesswork. Rated for pollution degree 3, so it holds up in industrial enclosures where conductive dust or condensation is present — no need for an additional conformal coating in a typical IP54 panel.
Environmental and Mounting
Operating temperature range -25 to +60 °C covers unheated plant floors and warm cabinet interiors; storage and transport limits exceed this, but the running derating above 40 °C follows the standard SIRIUS thermal curve. Front face carries IP20 protection — safe for finger contact behind a closed panel door. Side-by-side mounting is permitted without derating, saving rail space when stacking multiple contactors in a motor control center row.
