It guards motors against damage caused by sustained overload conditions and phase failure, tripping within Class 10 response times to limit thermal stress on the motor windings. The relay features built-in temperature compensation, a trip-free mechanism that prevents bypass of the protective function, and a clearly visible trip indication. The adjustable current range spans 1.3 to 1.7 amps, making it suited for smaller motor loads. Licensed electricians and motor control technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis relay is used in residential and light commercial motor control applications where compact, direct-mount overload protection is required. It mounts directly to compatible block contactors, simplifying panel assembly and reducing wiring complexity. The STOP function allows the relay to serve a dual role in the control circuit. Both automatic and manual reset modes are selectable, giving the installer flexibility based on the restart requirements of the application and local safety protocols.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable current range of 1.3 to 1.7 amps for precise motor protection\u003c\/li\u003e\n  \u003cli\u003eTrip Class 10 response for fast protection against overload conditions\u003c\/li\u003e\n  \u003cli\u003ePhase failure detection to prevent single-phasing damage to motors\u003c\/li\u003e\n  \u003cli\u003eTemperature compensation maintains consistent trip accuracy across ambient conditions\u003c\/li\u003e\n  \u003cli\u003eTrip contact (NC) and signal contact (NO) included for control circuit integration\u003c\/li\u003e\n  \u003cli\u003eSelectable automatic or manual reset and trip-free mechanism prevent unsafe restart\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for direct mounting to compatible block contactors in motor control assemblies.

De-energize and lock out the circuit before installing or adjusting the relay. Verify the current adjustment dial is set to match the motor full-load amperage rating before energizing. Confirm reset mode selection matches the application restart requirements prior to commissioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 1.3 to 1.7 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Class\u003c\/strong\u003e: Class 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Contact\u003c\/strong\u003e: NC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSignal Contact\u003c\/strong\u003e: NO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReset Mode\u003c\/strong\u003e: Automatic or manual, selectable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection Function\u003c\/strong\u003e: Overload and phase failure\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: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tf42-1.7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51620910399794,"sku":"TF42-1.7","price":112.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5330d3be5b81ba8f5efefec991f13008.jpg?v=1787347689","url":"https:\/\/voomisupply.com\/products\/abb-tf42-1-7-thermal-overload-relay-1-3-to-1-7-a","provider":"Voomi Supply","version":"1.0","type":"link"}
