It switches a single change-over contact at 24 V AC/DC coil voltage, rated for a thermal current of 6 A. The spring-loaded push-in terminal cuts wiring time on a DIN-rail panel — strip, push, done. At 6.2 mm wide, this relay packs into tight DIN-rail rows where every millimeter counts — common in control cabinets for packaging lines or conveyor sections. The 1 change-over contact handles signal-level switching or small auxiliary loads; the 6 A thermal current covers most PLC output and sensor interface duties without derating at 24 V. This part is listed as an active, current-production item. No end-of-life notice or successor has been issued. For a critical spare on a BOM, it remains a standard stocking line — order against an RFQ for lead time and quantity. RoHS compliant since 26 September 2024. REACH Article 33 information is available on request.","metaTitle":"Siemens 3RQ4018-2AB00 SIRIUS coupling relay, 24 V AC/DC, 1 C","metaDescription":"Siemens 3RQ4018-2AB00 SIRIUS 3RQ4 output coupler with integrated relay, 24 V AC/DC, 1 change-over contact, spring-loaded terminal, 6.2 mm wide, thermal current 6 A.
