Product Description

The SIEMENS Multi-Function Time Delay Relay is a DIN-Rail Mounted relay with an On Delay function. It operates on a 12 to 240V AC/DC input voltage and has a contact rating of 3 A @ 24/250/400V. This 7-pin/terminal device (MPN 3RP25051AW30) is designed for industrial control applications.

Frequently Asked Questions

What is the SIEMENS Multi-Function Time Delay Relay used for?

The SIEMENS Multi-Function Time Delay Relay is used in industrial control panels to introduce a preset delay before switching a load. It is commonly applied in motor start/stop sequences, conveyor timing, and HVAC system controls to prevent simultaneous startup or to sequence operations.

What are the specifications of the SIEMENS 3RP25051AW30 time delay relay?

The SIEMENS 3RP25051AW30 is a DIN-rail mounted relay with an On Delay function. It accepts a universal input voltage of 12 to 240V AC/DC and has a contact rating of 3 A at 24/250/400V AC. The device features 7 pins/terminals and is manufactured by Siemens.

Where to buy the SIEMENS 3RP25051AW30 relay worldwide?

You can source the SIEMENS 3RP25051AW30 relay worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to install a DIN-rail mounted time delay relay?

To install a DIN-rail mounted time delay relay, snap it onto a standard 35mm DIN rail. Connect the input voltage (12 to 240V AC/DC) to the designated terminals, wire the load to the output contacts (rated 3 A), and set the delay time via the front dial. Always follow the Siemens manual for wiring and safety.
