Siemens 3RP1505-1AP30 Low Voltage Soft Starter

Siemens 3RP1505-1AP30 is a multifunction timing relay in the SIRIUS 3RP family, designed to automate control sequences with precise time-based signals in industrial panels. This 3RP1505-1AP30 variant provides timing functions with a 240 V AC supply and an LED indicator for status at a glance, with screw-terminal wiring for reliable connections. It operates on standard 50/60 Hz power and is rated for ambient temperatures from -25 to +60 °C (storage -40 to +85 °C), with a maximum installation altitude of 2,000 meters. The unit’s front is protected to IP40 while the control terminals are IP20, making it suitable for general-purpose control-circuit applications in factories, machines, and conveyor systems. As part of Siemens’ SIRIUS lineup, the timing relay consolidates multiple timing functions in a compact package, enabling delayed switching, pulse shaping, and sequencing tasks in automation panels without requiring a separate timer module. Note: This device is a timing relay, not a soft starter, and is intended to provide controlled time-based signaling to downstream equipment.
