It carries 2 NO (instantaneous) contacts, each rated 10 A at 24 V, and is built into the S00 contactor frame size (45 mm wide, 60 mm tall, 73 mm deep). The 10 A at 24 V rating means it can handle the full coil inrush of multiple small contactors or a bank of solenoid valves without derating. For higher-voltage control circuits, the current drops: 6 A at 230 V, 3 A at 400 V, 1 A at 690 V — the typical AC-15 / DC-13 auxiliary contact curve for a relay of this size. Mounts via screw or snap-on to a DIN rail. The S00 footprint — 45 mm wide — is the smallest Siemens contactor frame, so it fits in tight panel layouts. RoHS compliant per the substance prohibition date of July 1, 2006. The built-in surge suppressor is a diode — verify polarity if the control circuit uses DC switching, because a diode clamps the reverse voltage but blocks one half-cycle on AC. Mechanical life is 30 million operations; contact reliability is rated at 1 incorrect switching per 100 million operations at 17 V, 1 mA — a dry-circuit spec that matters for PLC input signals.","metaTitle":"Siemens 3RH1122-2JC40-ZW95 SIRIUS Coupling Relay, S00, 10A a","metaDescription":"Siemens SIRIUS 3RH1122-2JC40-ZW95 coupling relay, size S00, 2 NO contacts, 10A at 24V, IP20, screw/snap-on mount, RoHS.
