It bridges identical potentials across adjacent relay positions, with a maximum infeed current of 10 A. This is the accessory that turns individual relay bases into a common potential rail — critical for reducing wiring in multi-relay control schemes. Mounts directly onto the SIRIUS 3RQ4 narrow coupling relay bases. The 8-pole comb spans eight adjacent relay positions, so it's sized for a standard row in a control panel. Panel builders use this to distribute a common supply voltage (e.g. 24 VDC) or a common signal return across multiple relays without daisy-chaining individual wires. Package dimensions are 95 x 93 x 65 mm — fits within the DIN-rail footprint of the relay assembly.","metaTitle":"Siemens 3RQ4901-0C SIRIUS 3RQ4 Connecting Comb, 8-pole, 10 A","metaDescription":"Siemens 3RQ4901-0C SIRIUS 3RQ4 connecting comb for coupling relays, narrow design. 8-pole, max infeed 10 A.

That is the total current the comb can carry from the feed point to all connected relay positions — not per-pole. For higher-current distribution, you would use a separate power terminal block or a heavier busbar."},{"question":"What compliance documentation is available for this part?","answer":"RoHS compliance is confirmed effective September 26, 2024.
