Siemens 3RT1016-1AR65 — SIRIUS S00 Power Contactor, 24 VDC Coil
Rated for AC-2 duty at 400 V at 4 kW and AC-4 at 400 V at 8.5 A, this contactor handles reversing and inching applications where the load is switched under full motor current. The 690 V rating at 5.5 kW extends its reach to 690 VAC line supplies common in heavy industrial installations. Mechanical endurance is rated at 30,000,000 operating cycles, reflecting the SIRIUS platform's design for high-duty-cycle applications like conveyor lines, pump stations, and compressor control.
Panel Integration & Mounting
Mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 50022. The 45 mm width and 57.5 mm height with a 114 mm depth fit standard DIN-rail enclosures. Side-by-side mounting is permitted, allowing dense panel layouts without additional spacing between contactors. Front protection is IP20; the terminal area is also rated IP20. Pollution degree 3 means it's suitable for industrial environments with conductive pollution — no additional conformal coating needed for typical panel conditions. Operating temperature range is -25 to +60 °C, with a maximum operating altitude of 2,000 m. 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. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. No special tooling required — standard screwdriver termination.
Coordination & Protection
For Type 2 coordination (no damage to the contactor after a short circuit), the required upstream fuse is gL/gG 20 A. For Type 1 coordination (contactor may need replacement after fault), the fuse rating is gL/gG 35 A. These values guide the selection of branch circuit protection when integrating into a motor control center or distribution panel. The 3RT1016-1AR65 is a 3-pole instantaneous contactor with no built-in overload relay — pair it with a separate SIRIUS 3RU2 or 3RB3 overload for motor protection.
