Siemens 3RP25 Series DIN Rail Timer Relay, 2-Contact, 250 V dc 12 V ac, 240 V ac, 1 to 20 s, 1-Function, DPST Switch

Achieve precise timing control over your electrical system with this timer relay from Siemens. When energised, its DPST (double pole single throw) setup lets it swap the current flow between two circuits after the predefined time. The unit features star-delta functionality, meaning that it activates a lower-voltage circuit before swapping to full voltage. This limits the inrush current through the circuit to less than 5A and makes the relay ideal for safely starting large electric motors. A 50ms changeover time between the unit's star and delta circuits minimises the risk of shorting to prevent harm to your operators and equipment.

• Wide programmable delay range between 1 and 20 seconds can be tailored to suit various systems

Inrush current refers to the current pulled by a motor-based appliance when initially activated. It's typically much higher than the normal operating current of the appliance.
