The four NO contacts switch instantaneously — there are no delayed, leading, or lagging contacts on this variant. That makes it a straight signal repeater: all four close at the same moment the coil picks up, with no sequencing for staggered load application. Storage and transport tolerance down to -55 °C is a handling spec, not a running condition. Strip length and ferrule sizing follow standard practice for the 0.5–2.5 mm² range; the 4 mm² entry handles larger PE or common-feed wires without pigtailing. Dimensions of 45 mm wide by 57.5 mm high by 72 mm deep place it in the S00 footprint shared across the SIRIUS 3RT2 contactor family. If you're replacing a 3RT1015-1AG61 or 3RT1016-1AG61 in an existing panel, the 3RH1140-1AK60-1AA0 occupies the same DIN-rail slot and wiring zone — no re-drilling or re-routing of the gland plate needed.","metaTitle":"Siemens 3RH1140-1AK60-1AA0 SIRIUS Auxiliary Contactor, 4 NO,","metaDescription":"Siemens SIRIUS 3RH1140-1AK60-1AA0 auxiliary contactor, size S00, 4 NO contacts, 10 A AC-12 at 24 V.

If you need an auxiliary contactor with 4 NO contacts, the 3RH1140-1AK60-1AA0 is the direct choice; the 3RT series siblings serve a different function and are not drop-in substitutes for control-signal switching."},{"question":"How do I get pricing and availability for 3RH1140-1AK60-1AA0?","answer":"This part is sourced and quoted to order through independent distribution.

The 3RH1140-1AK60-1AA0 drops into the same slot without rewiring or panel modifications, though you are replacing a power contactor with an auxiliary contactor, so verify the circuit function matches."},{"question":"What compliance documentation is available for 3RH1140-1AK60-1AA0?","answer":"As a standard Siemens SIRIUS catalog item, this contactor carries CE marking for the European market and is manufactured under IEC/EN 60947-5-1.
