The Siemens 3RP1540-1BJ31 is a SIRIUS time relay with a relay output and adjustable ON-delay spanning 0.05 to 600 s. It carries a thermal current rating of 5 A, and at 24 V DC the contact switches 1 A; at 125 V AC it switches 0.2 A, and at 250 V AC 0.1 A. The recovery time is 150 ms, with a minimum ON period of 200 ms.
The 22.5 mm width fits standard enclosure spacing; tightening torque is 0.8 to 1.2 N·m for the terminals. Stranded wire from 20 to 14 AWG is accepted.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The adjustable time range is 0.05 to 600 s, with a recovery time of 150 ms and a minimum ON period of 200 ms.
