It provides 4-pole earth-fault protection rated for 250 A operational current at 127-480 V AC, with selectable residual current thresholds from 30 mA to 5 A and selectable trip delay from 0 to 3000 ms. Includes 30% pre-alarm indication, sealable selectors, and switchable RCD-or-monitoring mode.\u003c\/p\u003e\n\u003cp\u003eTechnical specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOrder number (MLFB): 3VA9214-0RS20\u003c\/li\u003e\n\u003cli\u003eManufacturer: Siemens\u003c\/li\u003e\n\u003cli\u003eProduct line: SENTRON\u003c\/li\u003e\n\u003cli\u003eProduct type: Residual current protection module, Type A\u003c\/li\u003e\n\u003cli\u003eSeries: RCD510 basic\u003c\/li\u003e\n\u003cli\u003eCompatible circuit breakers: 3VA1 with terminal connection (e.g. 3VA12 Frame 250)\u003c\/li\u003e\n\u003cli\u003eMounting: Side mounted, screw fixing\u003c\/li\u003e\n\u003cli\u003eNumber of poles: 4\u003c\/li\u003e\n\u003cli\u003eOperational current (Ie): 250 A AC\u003c\/li\u003e\n\u003cli\u003eSupply voltage (Ue): 127-480 V AC\u003c\/li\u003e\n\u003cli\u003eOperating frequency: 50\/60 Hz (rated max 60 Hz)\u003c\/li\u003e\n\u003cli\u003eFault current frequency range: 50-60 Hz\u003c\/li\u003e\n\u003cli\u003eAdjustable rated residual current (IΔn): 0.03 \/ 0.05 \/ 0.1 \/ 0.3 \/ 0.5 \/ 1 \/ 3 \/ 5 A\u003c\/li\u003e\n\u003cli\u003eAdjustable non-tripping time (tv): 0 \/ 0.06 \/ 0.15 \/ 0.3 \/ 0.5 \/ 1.0 \/ 2.0 \/ 3.0 s\u003c\/li\u003e\n\u003cli\u003ePre-alarm indication: Yes, at 30% of IΔn setting\u003c\/li\u003e\n\u003cli\u003eSelectable RCD or monitoring mode: Yes\u003c\/li\u003e\n\u003cli\u003eElectrical trip indicator: Yes\u003c\/li\u003e\n\u003cli\u003eSealable selectors: Yes\u003c\/li\u003e\n\u003cli\u003eInfeed position on RCD module: Top or bottom\u003c\/li\u003e\n\u003cli\u003eRemote tripping: No\u003c\/li\u003e\n\u003cli\u003eCommunication function: No\u003c\/li\u003e\n\u003cli\u003eIP protection (front): IP40\u003c\/li\u003e\n\u003cli\u003eDimensions (H × W × D): 228 × 170 × 70 mm\u003c\/li\u003e\n\u003cli\u003eNet weight: 1.516 kg\u003c\/li\u003e\n\u003cli\u003eAmbient temperature during operation: -25 to +70 °C\u003c\/li\u003e\n\u003cli\u003eStorage temperature: -40 to +80 °C\u003c\/li\u003e\n\u003cli\u003eApprovals: General Product Approval, EMC, Maritime application, type test, environmental confirmations, dangerous-goods transport information\u003c\/li\u003e\n\u003cli\u003eEAN\/GTIN: 4042949002277\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFeatures and benefits:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType A residual current detection - covers pulsating DC fault currents in addition to AC, suitable for modern loads with rectifiers\/inverters\u003c\/li\u003e\n\u003cli\u003eWide adjustable thresholds 30 mA to 5 A - allows tuning from personal-protection to fire-protection use cases on the same hardware\u003c\/li\u003e\n\u003cli\u003eAdjustable time delay 0-3 s - selective coordination with downstream RCDs to prevent nuisance tripping\u003c\/li\u003e\n\u003cli\u003e30% pre-alarm indication - early warning of insulation degradation before actual trip\u003c\/li\u003e\n\u003cli\u003eSwitchable RCD\/monitoring mode - run as a true breaker OR as a monitoring-only relay for fault recording without tripping\u003c\/li\u003e\n\u003cli\u003eSide-mounted: doesn't increase the breaker footprint depth; preserves panel layout\u003c\/li\u003e\n\u003cli\u003eSealable settings - prevent unauthorized tampering with trip thresholds\u003c\/li\u003e\n\u003cli\u003eMaritime approval - usable on shipboard and offshore distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eApplications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEarth-fault protection on 3VA1 Frame 250 main and feeder circuit breakers in industrial and commercial distribution boards\u003c\/li\u003e\n\u003cli\u003eFinal distribution circuits requiring 30 mA personal protection (additional protection per IEC 60364-4-41)\u003c\/li\u003e\n\u003cli\u003eFire prevention applications using 300-500 mA threshold settings\u003c\/li\u003e\n\u003cli\u003eSelective TT\/TN-S systems requiring time-delayed S-type residual current protection\u003c\/li\u003e\n\u003cli\u003ePlants with frequency converters and rectifier loads where Type A detection is required\u003c\/li\u003e\n\u003cli\u003eMaritime and shipboard switchboards with earth-fault monitoring requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAlso known as: Siemens 3VA9214-0RS20, SENTRON RCD510 basic Type A 4P 250A, 3VA1 residual current module 30mA-5A, side-mounted RCD for 3VA12.\u003c\/p\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":57865602531592,"sku":"SMN3VA9214-0RS20","price":413.96,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/4351\/3096\/files\/siemens-3va9214-0rs20-sentron-rcd510-type-a-4p-250a-30ma-5a-for-3va1-6813695.jpg?v=1779394055","url":"https:\/\/gabbyelectric.com\/products\/siemens-3va9214-0rs20-sentron-rcd510-type-a-4p-250a-30ma-5a-for-3va1","provider":"Gabby Electric","version":"1.0","type":"link"}
