Siemens 3RH1122-2AP00-ZW97 — SIRIUS Auxiliary Contactor, Size S00
The IP20 front protection means it is safe for finger contact inside an enclosed panel — standard for control-gear compartments.
Ratings and Switching Capacity
The 3RH1122-2AP00-ZW97 provides two instantaneous NO contacts and no leading, lagging, delayed, or make-before-break contacts. This is a straightforward 2-pole normally-open auxiliary contactor — no time-delay or overlapping switching built in. Its rated operational currents span the control-voltage range: 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 6 A at 230 V is the typical rating for a 230 V AC control circuit feeding a PLC input or relay coil. The 10 A at 24 V covers DC control loads at the common panel voltage.
Shock resistance is 10g / 5 ms and 5g / 10 ms. Wire capacity for solid conductors is 2x (0.25... 2.5 mm²). The depth is 73 mm, height 60 mm, width 45 mm. This fits a standard 45 mm-wide DIN-rail slot — the same footprint as many S00 contactors and motor starters, so it drops into an existing panel layout without re-spacing.
