Siemens 3RH1122-1AK60 — SIRIUS Auxiliary Contactor, Size S00, 2 NO
It is rated for 10 A at 24 V and 6 A at 230 V, with a contact reliability of one incorrect switching operation per 100 million operations at 17 V, 1 mA.
Contact Configuration & Switching Capacity
This contactor provides exactly two NO main contacts with no leading, lagging, delayed, or make-before-break switching. The switching capacity varies by voltage: 10 A at 24 V, 1 A at 110 V, 0.27 A at 220 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The rated control supply voltage is 50 Hz (0.8 to 1.1 times rated) or 60 Hz (0.85 to 1.1 times rated). For a panel-builder, this means the contactor handles typical 24 VDC control signals comfortably at 10 A, but derates significantly at higher AC voltages — a key consideration when switching 400 V or 690 V auxiliary loads.
Panel Integration & Wiring
The 3RH1122-1AK60 accepts solid conductors in three size ranges: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm². The screw terminals are standard for SIRIUS S00 contactors. Shock resistance is 10g for 5 ms and 5g for 10 ms.
Compliance & Approvals
The 3RH1122-1AK60 is RoHS-compliant per the substance prohibition date of 01.07.2006. The product extension auxiliary switch is available as an add-on.
