It bridges identical potentials across adjacent relay sockets in a control panel, with an infeed current-carrying capacity of max 10 A. This is the part that lets you daisy-chain common supply rails without point-to-point wiring. ## Integration notes Packaged singly, dimensions 95 x 93 x 65 mm. Snaps onto the DIN rail alongside the 3RQ4 relay base; the comb bridges the supply terminals without additional jumpers. Verify the infeed point — the 10 A limit is at the feed-in, not per pole.","metaTitle":"Siemens 3RQ4901-0B SIRIUS 3RQ4 Connecting Comb, 4-pole, 10 A","metaDescription":"Siemens 3RQ4901-0B SIRIUS 3RQ4 coupling relay connecting comb, 4-pole, infeed max 10 A.
