It combines a delayed contact and an instantaneous contact to manage the switching sequence between star and delta connections, thereby enabling reduced-voltage motor start-up. The unit operates with a broad supply voltage range and is designed for compact control panels, providing reliable time-based switching with adjustable delay.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eElectronic timing relay — star-delta (wye-delta) function\u003c\/li\u003e\n\u003cli\u003eOutput contacts: 2 NO (one delayed, one instantaneous)\u003c\/li\u003e\n\u003cli\u003eAdjustable time delay: 3 … 60 s — selectable via front panel dial\u003c\/li\u003e\n\u003cli\u003eSupply voltage: 12 … 240 V AC or DC — wide flexibility for control circuits\u003c\/li\u003e\n\u003cli\u003eMounting: DIN-rail (standard 35 mm rail) — space-efficient panel installation\u003c\/li\u003e\n\u003cli\u003eCompact width: 22.5 mm — suitable for dense relay cabinets\u003c\/li\u003e\n\u003cli\u003eScrew-type terminals — secure and easy wiring\u003c\/li\u003e\n\u003cli\u003eLED status indicator — provides visual feedback on relay status\u003c\/li\u003e\n\u003cli\u003eDesigned for control and motor-starting applications (star-delta) — suitable for three-phase motor start control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArticle Number:\u003c\/strong\u003e 3RP2576-1NW30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e SIRIUS 3RP25 timing relays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Star-delta (wye-delta) time relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Voltage:\u003c\/strong\u003e 12 … 240 V AC\/DC, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime Delay Range:\u003c\/strong\u003e 3 … 60 s (adjustable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e 2 × NO — 1 delayed, 1 instantaneous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Current (Ie):\u003c\/strong\u003e 5 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated insulation voltage \/ pollution degree:\u003c\/strong\u003e 300 V \/ pollution degree 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurge Voltage Withstand:\u003c\/strong\u003e 4,000 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Service Life:\u003c\/strong\u003e ~10,000,000 switching cycles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Endurance:\u003c\/strong\u003e ~100,000 cycles (AC-15 \/ 230 V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Width:\u003c\/strong\u003e 22.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e DIN-rail (35 mm rail) or flat mounting with optional lugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Operating Temperature:\u003c\/strong\u003e –25 °C … +60 °C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Class (front):\u003c\/strong\u003e IP20 — for internal control-cabinet use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Terminals:\u003c\/strong\u003e Screw-type, for conductors ~0.5–2.5 mm²\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe 3RP2576-1NW30 is used in motor-control circuits requiring star-to-delta starting sequences to reduce inrush current at motor start-up.
