It provides one normally-open and one normally-closed contact pair, terminated with spring-loaded terminals — no screwdriver needed for wiring, which speeds panel assembly and reduces torque-check steps during commissioning. The 1 NO + 1 NC configuration covers basic feedback or interlocking in a single add-on block. RoHS compliant since October 2009, with REACH candidate-list disclosure available on request. No UL or CSA mark is listed in the evidence, so verify site-specific approval requirements before specifying for North American panels. Mounts on the front of the contactor or relay — no DIN-rail space consumed beyond the base device. The spring-loaded terminals are oriented for front-access wiring; strip length of 8–10 mm is typical for the cage clamp. The 37 x 40 x 53 mm package dimensions (L x W x H) fit within the envelope of the 3RT2/3RH2 family. Multi-unit packaging (50 pieces per order) suits line builds or panel-shop kitting. Because it is made to order, lead time is driven by the production batch cycle — plan procurement against the build schedule rather than expecting off-the-shelf availability.","metaTitle":"Siemens 3RH2911-2HA11-Z W98 Auxiliary Switch, 1NO+1NC, Sprin","metaDescription":"Siemens 3RH2911-2HA11-Z W98 auxiliary switch block, 1 NO + 1 NC, spring-loaded terminal, for 3RT2 contactors and 3RH2 contactor relays.
