The 10 A rated value at 24 V is the thermal continuous current of the contact block itself; the AC-15 figures govern the switching life when driving magnetic loads. ## Mirror contact and contact reliability for safety circuits The normally closed (NC) contact on this switch is a mirror contact per IEC 60947-4-1. That means the NC position is mechanically linked to the NO position so that when the NO welds shut, the NC cannot close — a requirement for safety-related feedback in emergency-stop and guard-monitoring circuits up to SIL 3 / PL e. ## DIN-rail footprint and panel integration At 10 mm wide and 66 mm deep, this is a single-width S00 auxiliary switch block that snaps onto the DIN rail directly. It is designed as the first laterally mountable block — it clips onto the left side of a SIRIUS contactor or contactor relay without additional hardware, adding one or two contact sets without expanding the panel width beyond the contactor's own footprint. The IP20 front protection means the terminals are finger-safe when wired, but the block is intended for inside an enclosure, not exposed to washdown.","metaTitle":"Siemens 3RH6911-1DA02 SIRIUS Auxiliary Switch, 10 mm, AC-15","metaDescription":"Siemens 3RH6911-1DA02 SIRIUS auxiliary switch, size S00, 10 mm width, snap-on DIN rail.
