Product details

SIRIUS contactor relay, size S00, 4 NO auxiliary contacts

The 3RH6140-1AF00 is a Siemens SIRIUS contactor relay — a control-circuit switching device, not a main power contactor. Size S00 means it fits the standard 45 mm width slot in the SIRIUS modular system, sharing the same 57.5 mm height and 73 mm depth profile as the matching S00 contactors. The AC coil draws 37 VA on pick-up and 5.7 VA holding, with a power factor of 0.8.

Rated operational currents across voltage levels

The 10 A figure at 230 V is the highest continuous rating; derate for higher voltages or DC loads per the AC-12/DC-12/DC-13 switching frequency limits of 1,000 operations per hour. Surge voltage resistance is rated at 6 kV, which aligns with basic insulation coordination for 400 VAC control panels per IEC 60947-5-1.

Mounting flexibility and environmental limits

The substance prohibition date of 05/01/2012 confirms RoHS compliance through the exemption sunset review cycle. AWG equivalents are 2 × (20 to 16), 2 × (18 to 14), and 2 × 12.

Lifecycle and compliance documentation

Siemens provides a declaration of conformity to IEC 60947-5-1 for this contactor relay series. RoHS compliance is documented per the substance prohibition date of 05/01/2012. No UL or CSA listing is recorded in the available spec data — verify site-specific approval requirements before panel certification.
