3RA2812-1DW10
The 3RA2812-1DW10 is an electronic time-delay relay with a power-off delay and requires an external control signal. It has a semiconductor output with screw terminals and a delay range of 0.05 to 100 seconds. It is only compatible with SIRIUS 3RT201, 3RT202 (S00/S0) and 3RH2 auxiliary contactors and has a built-in surge suppressor.
Product Positioning
The 3RA2812-1DW10 is an electronic time-delay relay from the Siemens SIRIUS 3RA28 series. Its function is to delay power-off and it requires a control signal input. It adopts a semiconductor output design and is only suitable for S00 and S0 specification contactors. It is a time delay control accessory designed specifically for small contactors.
Core Product Advantages and Features
Power outage delay control
The contactor outputs a signal only after a set time delay following power failure, making it suitable for delayed shutdown control.
Semiconductor output design
Replacing mechanical contacts with semiconductor components makes it suitable for circuits with high-frequency operation or long lifespan requirements.
Specifically designed for S00/S0
The size and contact design are compatible with small 3RT201 and 3RT202 contactors, and the installation is seamless and requires no processing.
Built-in surge suppressor
It effectively suppresses the surge voltage generated when the contactor coil is de-energized, protecting the control circuit components.
