Product Positioning

The 3RA2813-2FW10 is a solid-state delay auxiliary switch from the Siemens SIRIUS 3RA28 series. Its function is to delay switching of the output contacts after the control voltage is applied. The spring terminal version is convenient for control panel applications with quick wiring.

Core Product Advantages and Features

Power-on delay function

The output contacts activate after a delay following the application of control voltage, making it suitable for sequential start-up control.

Spring-type terminals

Wiring can be completed without screws, making it suitable for a large number of repetitive assembly operations.

1NC plus 1NO dual contact

It provides both normally closed and normally open outputs to accommodate different control logic requirements.

Wide adjustable delay range

The delay settings range from 0.05 to 100 seconds, suitable for various sequential control scenarios.
