Thermal units provide overcurrent protection by responding to heat generated by excess current flow through the circuit. When current exceeds the rated threshold, the thermal element trips the overload relay, interrupting the control circuit and protecting downstream motors and equipment from damage. This part is typically installed by licensed electricians and HVAC technicians working on motor control and load-management systems.\u003c\/p\u003e\n\u003cp\u003eThe A14.1 thermal unit is suited for light commercial and industrial motor control applications where overload protection is required. It is installed into an overload relay block that is mounted on or associated with a contactor assembly. Typical install scenarios include motor starters in HVAC equipment, pump panels, and other motor-driven systems requiring thermal overload protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProvides thermal overcurrent protection for motor control circuits\u003c\/li\u003e\n  \u003cli\u003eInstalls directly into compatible overload relay blocks\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 2.4 inches long, 1.2 inches wide, 0.8 inches tall\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds for easy handling during installation\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement unit for serviceability in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement thermal unit for use with compatible SQUARE D overload relay blocks and contactor assemblies.

De-energize and lock out the control panel before removing or installing any thermal unit. Verify that the replacement thermal unit matches the required trip rating for the motor load before inserting into the overload relay block. Do not bypass or substitute thermal units with mismatched ratings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A14.1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542841950514,"sku":"A14.1","price":29.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/711643bed0fae375888eb69ab8f16262_87f20200-fda5-4547-9a5e-db496ef97f7e.jpg?v=1785908936","url":"https:\/\/voomisupply.com\/products\/square-d-a14-1-contactor-thermal-unit","provider":"Voomi Supply","version":"1.0","type":"link"}
