The adjustable time range from 0.05 to 100 s covers both short process interlocks and longer sequence delays, so the same relay can handle a quick conveyor stop or a multi-minute pump cycle. The thermal current rating of 5 A is the continuous current the relay contacts can carry in free air — this is the limit for resistive loads; inductive loads will need derating based on the specific contact ratings at 24 V (1 A), 125 V (0.2 A), and 250 V (0.1 A). The control supply voltage is 42-48 V AC/DC, so it fits standard 48 V control circuits common in industrial panels. The 22.5 mm width saves rail space — useful when packing multiple monitoring functions into a crowded enclosure.","metaTitle":"Siemens 3RP1555-2AR30 SIRIUS Monitoring Relay, 42-48V AC/DC,","metaDescription":"Siemens 3RP1555-2AR30 SIRIUS monitoring relay.
