3RP1560-1SP30 SIEMENS

The 3RP1560-1SP30 timing relay from Siemens is an electronic, phased-out product designed for star-delta (wye-delta) motor starting applications. This relay provides a timing function ranging from 1 to 20 seconds, allowing for precise control during the transition from star to delta configuration. It also features an overshoot time setting adjustable between 30 and 600 seconds, ensuring a smooth and controlled motor acceleration. The relay operates within a wide voltage range, supporting 0.85 to 1.1 times the rated voltage (US) at 24 V AC/DC, as well as 200 to 240 V AC at 50/60 Hz. Electrical connections are facilitated through convenient AC screw terminals, simplifying installation and maintenance. While this particular model is phased out, it represents Siemens' commitment to reliable and efficient motor control solutions. For detailed information on suitable replacements or alternative products, it is recommended to contact the Siemens sales department. This relay was commonly used in industrial applications to reduce inrush current during motor startup, protecting both the motor and the electrical grid. Its robust design and adjustable parameters made it a versatile choice for various motor control scenarios.
