Product details

The Siemens 3RP1555-2AP30 is a SIRIUS timing relay with a relay output, adjustable from 0.05 to 100 seconds. It operates on a 200-240 VAC supply at 50 or 60 Hz, making it a direct drop-in for standard European and North American control voltages. Rated thermal current of 5 A; switching capacity at 24 VDC is 1 A, at 125 VDC 0.2 A, and at 250 VDC 0.1 A. Recovery time is 150 ms — factor that into cyclic timing sequences.

Integration notes

Width is 22.5 mm, depth 91 mm, height 84 mm — occupies a single DIN-rail module. The solid and stranded wire range is 24-16 AWG, compatible with standard control wiring. Basic insulation, pollution degree 3 — suitable for industrial panel environments.

Frequently asked questions

Where can I buy the 3RP1555-2AP30 and get a price?

The 3RP1555-2AP30 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the 3RP1555-2AP30's time adjustment range?

The time delay is adjustable from 0.05 to 100 seconds.

What supply voltage does the 3RP1555-2AP30 require?

It operates on 200-240 VAC at 50 or 60 Hz.

Does the 3RP1555-2AP30 have ON-delay or OFF-delay?

This relay has delayed switching (adjustable) but no dedicated ON-delay or OFF-delay mode; it is not a star-delta timer.
