Product details

Time-Delay Relay for Control Circuits

The Siemens 3RP1505-1AW30 is a SIRIUS time-delay relay that combines ON-delay and OFF-delay functions in a single 22.5 mm wide housing, adjustable from 0.05 to 100 s via a front-panel potentiometer. The relay output switches up to 5 A thermal current, with contact ratings of 1 A at 24 V, 0.2 A at 125 V, and 0.1 A at 250 V — enough for pilot-duty loads like contactor coils, solenoid valves, or indicator lamps in a control cabinet.

DIN-Rail Mounting and Panel Fit

Tightening torque for the screw terminals is 0.8 to 1.2 N·m, accepting solid or stranded wire 20...14 AWG.

Frequently asked questions

What is the adjustable time range of 3RP1505-1AW30?

The adjustable time range is 0.05 to 100 seconds, covering both ON-delay and OFF-delay functions.

What supply voltage does 3RP1505-1AW30 accept?

It accepts 24 to 240 V AC at 50/60 Hz and 24 to 240 V DC, a universal range that simplifies stocking for mixed-voltage panels.

What is the contact rating of 3RP1505-1AW30?

Thermal current is 5 A; contact ratings are 1 A at 24 V, 0.2 A at 125 V, and 0.1 A at 250 V — suitable for pilot-duty loads in control circuits.
