Sized for installation with Siemens 3RU2 contactors (Size S2), it uses screw terminals for the main circuit and for the auxiliary circuit, and offers a Manual-Automatic-Reset option for how the device recovers after a trip. This relay is intended for motor protection in industrial panels and is commonly used with conveyors, pumps, fans, and other general-purpose motors in protected motor circuits. The 3RU2136-4BD0 variant is one of several 3RU2 models that share core construction and mounting with the same family, distinguished by its 14–20 A setting and the corresponding terminal configuration, enabling straightforward integration into existing Siemens control architectures.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268125806826,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3ru2136-4bd0-thermal-overload-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
