Siemens 3RP25 Series DIN Rail Timer Relay, 2-Contact, 200/240/380/440V AC, 3 to 60 s, DPST, 5A, 3RP2576-2NM20

The Siemens 3RP2576-2NM20 timer relay from the 3RP25 series delivers precise time-delayed switching in industrial automation and pilot control circuits. With selectable time range of 3 to 60 seconds, the relay provides optimized performance for star-delta motor starting, sequential process control, and other timed switching applications in manufacturing, HVAC control panels, and process industries.

This DIN-rail mount relay supports four wide AC supply voltages: 200V, 240V, 380V, and 440V, accommodating various international standards and plant requirements. Its 2-contact DPST output design ensures robust handling of up to 5A load currents, and makes it a versatile solution for multiple loads or signal tasks.

Offers a selectable time range from 3 to 60 seconds for flexible timing control. Supports a wide supply voltage of 200V, 240V, 380V, and 440V AC for global application compatibility. Features a double pole single throw (DPST) contact configuration for secure switching operations.

Compact DIN rail mountable form factor, ideal for modern panel designs. Robust 5A contact current rating ensures safe operation with industrial loads. IP20 protection rating safeguards against solid objects and touch. Push-in terminal type for convenient installation and wiring.

Operates in temperatures ranging from -25°C to 60°C for tough environments.

The relay's star-delta timing mode is especially suited for reducing inrush currents and mechanical stresses during three-phase motor startup. A clear LED status indicator simplifies troubleshooting, while a front-panel selector switch enables intuitive time adjustment.

Built to demanding industrial standards (UL, IEC 61812-1, IEC 60664, IEC 60529, IEC 60068-2-27, EN 954-1), the Siemens 3RP2576-2NM20 offers proven reliability and safety. Its push-in connection terminals speed up installation and maintenance, and its slim housing (22.5mm wide, 100mm high, 91.6mm deep) minimizes panel space requirements.

Common applications include machinery control panels, conveyor systems, manufacturing automation, motor protection schemes, and building HVAC controls. The relay is suitable for industrial, commercial, and laboratory uses where timing precision and reliability are critical.
