Product details

The Siemens 3RP1555-2AQ30 is a SIRIUS timing relay — a single-function ON-delay unit with an adjustable time range of 0.05 to 100 s. It switches its relay output at the end of the set delay, with a recovery time of 150 ms between cycles. The control supply is 100-127 V AC at 50 or 60 Hz, and the contacts are rated for a thermal current of 5 A, switching 1 A at 24 V DC, 0.2 A at 125 V DC, or 0.1 A at 250 V DC.

Mounts on a 35 mm standard DIN rail via the integrated snap-on latch, with screw terminals for wiring.
