The Siemens 3RP1576-1NP30 is a sophisticated timing relay designed for a variety of industrial applications. This electronic component is a phased-out product, which means it holds significant value for maintenance or replacement in existing systems where continuity is essential. It features a star-delta (wye-delta) function, which is crucial for applications requiring the reduction of the initial voltage during motor start-up, thereby minimising mechanical stress and current spikes.
This timing relay comes with a single changeover contact that is delayed, and an additional instantaneous contact, providing flexibility in control circuit design. It offers a time range of 3 to 60 seconds, which can be precisely set to meet the specific timing requirements of your application. The control supply voltage is versatile, accepting 24 V AC/DC and 200 to 240 V AC at 50/60 Hz, making it suitable for a wide range of operating environments.
The 3RP1576-1NP30 is designed with user convenience in mind, featuring screw terminals for secure and reliable connections. Its compact dimensions allow for efficient use of space within control panels, and it can be mounted easily with screw or snap-on mounting onto a 35 mm standard mounting rail. With an insulation voltage rated at 300 V and a surge voltage resistance of 4,000 V, this timing relay is built to withstand challenging industrial conditions.
The relay's robust construction ensures a mechanical service life of typically 10 million switching cycles and an electrical endurance of 100,000 cycles at AC-15 at 230 V, highlighting its durability and reliability. Additionally, the relay is designed to operate within a temperature range of -25 to +60 degrees Celsius, ensuring performance stability in varying climates.
Overall, the Siemens 3RP1576-1NP30 timing relay is an essential component for industrial automation systems requiring precise timing control, particularly in scenarios where star-delta starting is necessary. Its robust design and flexible features make it a valuable asset for maintaining the efficiency and reliability of your machinery and processes.
