The base provides secure mechanical mounting and reliable electrical connection between the relay and the control circuit. It measures 2.913 inches long by 1.654 inches wide by 1.063 inches tall and weighs 0.134 pounds, making it compact enough for dense panel layouts. Electricians and controls technicians install this component as part of low-voltage relay logic, HVAC controls, and industrial automation systems where a socketed relay mounting point is required.\u003c\/p\u003e\u003cp\u003eThis relay base is suited for use in residential and commercial control panel builds, equipment control circuits, and building automation installations. It accepts the corresponding LZS series relay insert, allowing the relay to be swapped without disturbing field wiring. This design is common in HVAC system controllers, fan coil unit wiring panels, and other 24-volt or low-voltage relay applications where maintainability is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSocketed base design allows relay replacement without rewiring field connections\u003c\/li\u003e\n\u003cli\u003eCompact footprint at 2.913 x 1.654 x 1.063 inches for dense panel installations\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.134 pounds\u003c\/li\u003e\n\u003cli\u003eDesigned for use with LZS series plug-in relays\u003c\/li\u003e\n\u003cli\u003eSuitable for low-voltage control circuit applications in HVAC and building automation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style socket base for use with SIEMENS LZS series plug-in relays in control panel and automation wiring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified controls technician. De-energize and lock out the control panel before mounting or removing the relay base. Secure field wiring to the base terminals before inserting the relay, and verify terminal torque and wire gauge comply with the panel documentation and applicable NEC requirements. Do not install or remove the relay under live voltage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.913 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.654 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.134 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455495039\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LZS:PT78740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383615586610,"sku":"LZS:PT78740","price":28.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677239.jpg?v=1782602251","url":"https:\/\/voomisupply.com\/products\/siemens-lzs-pt78740-relay-base-lzs-series","provider":"Voomi Supply","version":"1.0","type":"link"}
