It incorporates phase‑failure sensitivity and is designed to mount directly onto Siemens contactors and motor starters, providing a dedicated trip path and status feedback within the control panel. The 3UA59 family supports IEC 60947-4 protections and is intended for integration into Siemens protection schemes for reliable motor protection, with the 00 2B variant specifically targeting 12.5–20 A applications; other 3UA59 variants cover higher current ranges such as 20–32 A. In operation, the relay monitors motor current and will interrupt the circuit when overload or phase imbalance is detected, enabling quick protection of connected equipment and aligning with Siemens interconnection practices for straightforward replacement and diagnostics.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268181446890,"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-3ua59-00-2b-overload-relay-12-5-to-20-amp","provider":"GTG Hardware","version":"1.0","type":"link"}
