At 10 mm wide, 64.8 mm tall, and 66 mm deep, it tucks into the same envelope as the contactor itself. The IP20 front protection is standard for enclosed panel gear — no washdown rating here, so keep it behind a gland plate or enclosure door. It carries a mirror contact per IEC 60947-4-1 when used with 3RT2 contactors. That means the normally closed contact mechanically mirrors the main contactor's state — critical for safety circuits where you need positive indication that the power contacts have opened. That's a solid number for PLC input sensing. The leading and lagging contacts are both zero — meaning all contacts switch simultaneously, no overlap timing for sequenced signaling. Terminals accept 2 x (0.5 to 2.5 mm²) solid or stranded, or 2 x (20 to 14 AWG). For finely stranded wire with ferrule, it's 2 x (0.5 to 1.5 mm²). Substance prohibition date is 10/01/2009, which aligns with the original EU RoHS directive (2002/95/EC). The part is RoHS-compliant as shipped. No UL or CSA listing appears in the evidence, but the IEC 60947-4-1 mirror contact reference implies it is designed to that international standard. For a compliance pack, request the manufacturer's declaration from your sourcing contact.","metaTitle":"Siemens 3RH2911-2DA02-ZX95 SIRIUS Auxiliary Switch, 10 A at","metaDescription":"Siemens SIRIUS 3RH2911-2DA02-ZX95 auxiliary switch.
