It's a phased-out product, with the official successor being the SIRIUS 3RH2 series — a key fact for any BOM line that needs a long-term supply commitment. The coupling link carries one normally-open (NO) auxiliary contact, rated 1 A at 24 V DC, 0.2 A at 110 V DC, and 0.1 A at 220 V DC. For AC loads, the contact handles 3 A at 230 V. These are the maximum switching currents at those voltages — the actual load in your control circuit must stay within these limits, especially at higher DC voltages where arc extinction is harder. It fits contactor frames S0 and S2 (the SIRIUS compact range up to about 40 A motor full-load current). The coupling link fastens via direct mounting — no DIN rail or additional bracket needed — and can be installed in any orientation. The terminals accept two conductors per clamp: 0.5 to 1.5 mm² with core-end processing, or 0.75 to 2.5 mm² solid.","metaTitle":"Siemens 3RH1924-1GP11 SIRIUS coupling link, 24 V DC, S0-S3","metaDescription":"Siemens SIRIUS 3RH1924-1GP11 coupling link for direct coil mounting on contactors sizes S0-S3, 24 V DC.
