The AC-15 current ratings drop as voltage rises: 6 A at 230 V, 3 A at 400 V, 1 A at 690 V. The AC-12 maximum of 10 A at 24 V is the resistive limit; don't plan on switching a 10 A solenoid at 24 V, because the inductive inrush will exceed the AC-15 rating. The mechanical service life of 10 million operating cycles is typical for a SIRIUS block — it will outlast the contactor in most cyclic applications. Snap-on mounting to the front of the contactor or contactor relay — no tools needed. The block is sized for S00 frames (3RT2, 3RT1). It accepts 2 x (0.5 to 1.5 mm²) solid or stranded, or 2 x (0.75 to 2.5 mm²) with ferrules; AWG equivalents are 2 x (20 to 16) and 2 x (18 to 14). The product design also allows snapping onto the front of a 3RH2140 or 3RH2440 auxiliary switch block for stacking additional contacts.","metaTitle":"Siemens 3RH1911-1GA31-ZW97 SIRIUS Auxiliary Switch, 3 NO, 41","metaDescription":"Siemens SIRIUS 3RH1911-1GA31-ZW97 auxiliary switch, 3 instantaneous contacts, AC-15 rated 6 A at 230 V, snap-on for S00 contactors.
