It provides 1 normally open and 3 normally closed contacts, rated at 10 A at 24 V, and mounts via snap-on to a DIN rail or directly onto a contactor. The auxiliary contacts are rated for AC-15 duty at 690 V at 1 A, and the block carries a surge voltage resistance of 6 kV. The contact reliability specification — one faulty switching per 100 million operations at 17 V, 5 mA — means it is suitable for low-energy signal circuits where oxide buildup on standard contacts can cause intermittent failures. ## Integration Notes Screw-type terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) conductors with core end processing, or 2x (20 to 16) and 2x (18 to 14) AWG. Mechanical service life is 10 million switching cycles. The 36.5 mm width and 41.5 mm depth fit standard panel layouts.","metaTitle":"3RH1911-1HA13-ZX95 SIRIUS Auxiliary Switch Block, 10 A, Phas","metaDescription":"Siemens SIRIUS 3RH1911-1HA13-ZX95 auxiliary switch block, 1 NO + 3 NC, 10 A at 24 V.
