It extends the switching capability of the base device by adding auxiliary contact positions without increasing the overall footprint of the assembly. Licensed electricians and industrial controls technicians install this accessory during panel builds, motor control center (MCC) upgrades, and equipment maintenance. At 0.037 pounds and compact dimensions of 1.811 inches x 1.457 inches x 0.551 inches, the block fits into tight enclosures where space is at a premium.\u003c\/p\u003e\n\u003cp\u003eThis auxiliary contact block is suited for industrial and commercial electrical control applications where additional signaling, interlock, or status-monitoring contacts are required alongside a motor protection circuit breaker or manual motor starter. It is supplied as a single unit per pack and is intended for snap-on transverse mounting, making it a straightforward addition during initial assembly or field service without requiring specialized tooling beyond what a standard electrician carries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransverse mounting orientation for lateral installation on compatible base devices\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 1.811 inches x 1.457 inches x 0.551 inches\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.037 pounds — suitable for dense panel layouts\u003c\/li\u003e\n  \u003cli\u003eSnap-on design supports efficient field installation and replacement\u003c\/li\u003e\n  \u003cli\u003eSingle unit per pack for straightforward inventory and ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style transverse auxiliary contact block for compatible Siemens motor starter and motor protection circuit breaker assemblies.

De-energize and lock out the circuit before attaching or removing any auxiliary contact block. Confirm the transverse mounting slot on the base device is clear and unobstructed before snapping the block into position. Do not force the block into place; misalignment can damage the contact mechanism.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Transverse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.457 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.551 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 66264392480\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3RV29012E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383221059890,"sku":"3RV29012E","price":62.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676883.jpg?v=1782590093","url":"https:\/\/voomisupply.com\/products\/siemens-3rv29012e-transverse-auxiliary-contact-block","provider":"Voomi Supply","version":"1.0","type":"link"}
