Open type construction means the core and coil assembly is exposed, making it suitable for enclosure mounting in panels, control boxes, and equipment cabinets where the surrounding enclosure provides environmental protection. Licensed electricians and HVAC controls technicians install this class of transformer when converting line voltage to a lower control-circuit voltage. The open frame design allows for straightforward integration into custom enclosures and OEM equipment builds.\u003c\/p\u003e\n\u003cp\u003eThe VT57A is suited for residential and light commercial control circuit applications where a compact, open type transformer is required. Typical installations include HVAC control panels, industrial control enclosures, and low-voltage distribution systems. The open type form factor makes it a common choice for OEM equipment manufacturers and panel builders who integrate the transformer into a larger assembly with its own enclosure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOpen type core and coil construction for panel and enclosure mounting\u003c\/li\u003e\n  \u003cli\u003eSuitable for control circuit and low-voltage distribution applications\u003c\/li\u003e\n  \u003cli\u003eCompact form factor supports integration into custom control enclosures\u003c\/li\u003e\n  \u003cli\u003eDesigned for residential and light commercial electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation transformer for control circuit and low-voltage panel applications requiring an open type construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out all circuits before beginning work. Ensure the enclosure or panel housing the transformer provides adequate environmental protection, as the open type construction offers no built-in ingress protection. Verify input and output voltage ratings match the circuit requirements before energizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction Type\u003c\/strong\u003e: Open Type\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 62398095280\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: HAMMOND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VT57A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAMMOND","offers":[{"title":"Default Title","offer_id":51383946871090,"sku":"VT57A","price":84.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675727.jpg?v=1782612760","url":"https:\/\/voomisupply.com\/products\/hammond-vt57a-open-type-transformer","provider":"Voomi Supply","version":"1.0","type":"link"}
