SIRIUS auxiliary contactor, size S00 — 6 NO, snap-on mount
The Siemens SIRIUS 3RH1362-1CB00-0KA0 is a size S00 auxiliary contactor with six normally-open instantaneous contacts and a built-in varistor surge suppressor. It mounts via screw or snap-on onto a DIN rail, occupying a 45 mm wide footprint in the panel. The front face carries an IP20 protection class, safe for finger access in a live enclosure.
Contact ratings and switching capability
Each NO contact is rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — covering control circuits from low-voltage DC to 690 VAC line signals. The contact reliability specification guarantees fewer than one incorrect switching operation per 100 million operations at 17 V, 1 mA, which matters for PLC-level dry circuits where oxide films on silver contacts can cause intermittent opens.
Mechanical endurance and environmental tolerance
Mechanical life is rated at 10 million operating cycles typical. The contactor survives shock loads of 10g / 5 ms and 5g / 10 ms, and operates across -25 to +60 °C ambient. Storage and transport range extends to -55 to +80 °C. Mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° forward/backward tilt.
Wiring and compliance
Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². The part is RoHS-compliant per the substance prohibition date of July 1, 2006. Pollution degree 3 rating means it's suitable for industrial environments with conductive pollution.
