Siemens 3RP1525-1BQ30 C01 Soft Starter Module

Siemens 3RP1525-1BQ30 C01 timer relay, a DIN-rail mounted member of the Sirius 3RP15 family, provides ON-delay timing with two changeover contacts (DPDT) for compact control panel sequencing. It uses a 24 V DC coil and offers a timing range from 1.5 to 30 seconds, enabling precise delays before energizing downstream devices such as relays, contactors, or interlocks. The 3RP1525-1BQ30-2CO configuration delivers two independent changeover circuits, allowing parallel switching within a single module. On the load side, it can switch AC voltages up to 127 VAC, making it suitable for controlling line-voltage equipment from a low-voltage control circuit. Designed for straightforward DIN-rail installation, this relay fits standard industrial enclosures and panel layouts, supporting reliable startup sequencing, delayed activation of auxiliary circuits, and simple interlock logic in automation or machine-control scenarios.
