It provides 2 normally-open and 2 normally-closed contacts, with the current path arranged as 1 NO, 1 NC, 1 NC, 1 NO — the terminal numbering follows the standard.3/.4.1/.2 pattern. ## Terminal and contact configuration The contact arrangement is 2 NO + 2 NC, with the current path explicitly listed as 1 NO, 1 NC, 1 NC, 1 NO. This matters for schematic traceability: the first NO and first NC share the same coil-side potential, while the second pair mirrors the first. When wiring a reversing contactor or star-delta starter, confirm the terminal numbering (.3/.4 for NO.1/.2 for NC) matches your CAD macro — the 3RH2 family uses a consistent numbering scheme, so a macro from a standard 3RH2 block should transfer directly. ## Integration with contactors The block clips onto the front of any 3RT2 contactor or 3RH2 contactor relay. No additional mounting hardware or DIN-rail space is consumed — it sits within the contactor's own envelope. The spring-loaded terminals accept 0.2–2.5 mm² conductors (typical for control circuits), and the strip length should be 8 mm for reliable cage engagement. For panel builders, the packaging unit is 1 piece, but the description notes a pack size of 321 units for bulk orders — verify the ordering quantity with your distributor.","metaTitle":"Siemens 3RH2911-2FA22-Z X95 Auxiliary Switch, 2NO+2NC, Sprin","metaDescription":"Siemens auxiliary switch block for 3RT2 contactors and 3RH2 contactor relays. 2 NO + 2 NC, spring-loaded terminals.
