Rated at 30 amps with a load voltage range of 48 to 600 volts AC and a DC control input of 4 to 30 volts, this relay provides reliable, contact-free switching without mechanical wear. The blocking voltage is rated at 1200 volts, offering headroom for transient protection. Screw-type terminals simplify field wiring. Licensed electricians and industrial controls technicians are the primary installers of this device in panel and machine control environments.\u003c\/p\u003e\n\u003cp\u003eThis relay suits 3-phase motor control, heating element switching, and industrial automation panels where silent, maintenance-free operation is required. It operates with 2-phase control logic and is housed in a compact DIN-rail-compatible form factor. Applications span commercial and light industrial environments where a low-voltage DC signal must switch a higher-voltage 3-phase AC load without relay chatter or contact degradation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30 amp continuous load current rating\u003c\/li\u003e\n  \u003cli\u003eLoad voltage range: 48 to 600 volts AC\u003c\/li\u003e\n  \u003cli\u003eControl input: 4 to 30 volts DC, 2-phase controlled\u003c\/li\u003e\n  \u003cli\u003eBlocking voltage rated at 1200 volts for transient tolerance\u003c\/li\u003e\n  \u003cli\u003eScrew-type terminals for secure, field-serviceable wiring\u003c\/li\u003e\n  \u003cli\u003e3-phase switching with no moving contacts for long service life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM and replacement solid state relay for 3-phase industrial control panels and machine automation systems requiring a 4-30 V DC input signal and 48-600 V AC load switching capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the panel before removing or installing the relay. Solid state relays generate heat under load — verify that adequate thermal management, such as a heat sink or forced-air cooling, is in place before commissioning. Do not exceed the rated load current or blocking voltage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Current\u003c\/strong\u003e: 30 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Voltage\u003c\/strong\u003e: 48 to 600 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Input Voltage\u003c\/strong\u003e: 4 to 30 volts DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Phases\u003c\/strong\u003e: 3 Phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Method\u003c\/strong\u003e: 2-phase controlled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlocking Voltage\u003c\/strong\u003e: 1200 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Screw-Type Terminals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.320 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Germany\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: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3rf2230-1ab45\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51267976397106,"sku":"3RF2230-1AB45","price":324.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912940.png?v=1780695990","url":"https:\/\/voomisupply.com\/products\/siemens-3rf2230-1ab45-solid-state-relay-30a-3-phase","provider":"Voomi Supply","version":"1.0","type":"link"}
