{"product_id":"ba903812","title":"BA9038.12 Dold","description":"\u003cp\u003ethermistor motor protection relay, Protection Function: It protects motors from thermal overloads caused by high starting frequency, heavy starts, phase faults, insufficient cooling or high ambient temperatures., Sensor Inputs: It has an entrance for connecting up to 6 PTC resistors or bimetallic contacts in series., Working Principle: When the total resistance of the sensors reaches a specific threshold value (response value ≥ 3 kΩ), the output relay de-energizes (closed-loop operation)., Cable Break Detection:, Output Contacts: The \".12\" model is specifically equipped with two changeover contacts (switches), Reset: Depending on the exact variant (e.g. with or without the suffix \"\/100\"), it may include a thermal or electromagnetic reclosing (manual reset) lock, which requires manual intervention to reset the unit once, Auxiliary Voltage (Uh): The supply voltage varies depending on the specific part number (e.g. AC 42V, AC\/DC 110-230V, etc.)\u003c\/p\u003e","brand":"Dold","offers":[{"title":"Default Title","offer_id":42862054113364,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/2986\/0180\/files\/05_12_2025_18_56_17_BA9038.12_Dold.png?v=1769207876","url":"https:\/\/catalog.industrialautomationco.com\/products\/ba903812","provider":"IAC Catalog","version":"1.0","type":"link"}
