Overload relays monitor motor current and trip the circuit when sustained overcurrent conditions threaten motor windings. This unit mounts as part of a contactor assembly, providing thermal or electronic overload protection in motor starter configurations. Licensed electricians and industrial controls technicians install this device as part of a complete motor control center or standalone starter panel. Its Size S2 frame suits mid-range motor starters and pairs with corresponding Size S2 contactors.\u003c\/p\u003e\u003cp\u003eThe 3RU1936-3AA01 is used in industrial and commercial motor control applications where overload protection is required for three-phase motors. It is suited for installation in motor control centers, starter panels, and machine control enclosures. This relay is typically specified in manufacturing, HVAC plant rooms, pump stations, and similar facilities requiring reliable motor overload protection at the Size S2 contactor frame level.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSize S2 frame for compatibility with mid-range contactor assemblies\u003c\/li\u003e\n\u003cli\u003eProvides motor overload protection to prevent winding damage from sustained overcurrent\u003c\/li\u003e\n\u003cli\u003eDirect mounting to corresponding Size S2 contactors for compact starter assemblies\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for panel and motor control center installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style overload relay for Size S2 motor starter and contactor assemblies in industrial control applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the panel or motor control center before mounting or wiring this relay. Verify that the contactor frame size matches Size S2 before assembly. Do not exceed the rated current setting range for the connected motor load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size\u003c\/strong\u003e: S2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.388 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 4.803 x 2.402 x 4.882 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 04089256812\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3RU1936-3AA01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383404921138,"sku":"3RU1936-3AA01","price":64.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676917.jpg?v=1782595528","url":"https:\/\/voomisupply.com\/products\/siemens-3ru1936-3aa01-overload-relay-size-s2","provider":"Voomi Supply","version":"1.0","type":"link"}
