It takes a 230 V AC/DC control signal on the input side and switches one change-over contact rated for 6 A thermal current. The hard gold-plated contacts handle low-level signals reliably — that plating matters when you're switching dry circuits or PLC-level logic where standard silver contacts would oxidize and fail to make contact. At 6.2 mm wide, it takes up one module slot — useful when you're packing multiple isolation points into a tight enclosure. The narrow design means you can fit roughly 16 of these per 100 mm of rail, which matters for panel fill factor. ## Compliance and regulatory RoHS compliant since September 2024. Export control is straightforward: AL N / ECCN EAR99, no special licensing required.","metaTitle":"Siemens 3RQ4038-1AF01 SIRIUS 3RQ4 Coupling Relay, 230 V AC/D","metaDescription":"Siemens 3RQ4038-1AF01 SIRIUS 3RQ4 coupling relay, 230 V AC/DC input, 1 CO contact, 6 A thermal current, 6.2 mm wide.
