It operates on a 200-240 V supply at 50 or 60 Hz, with an adjustable time range of 1 to 20 seconds. The relay output switches loads up to 5 A thermal current, with contact ratings of 1 A at 24 VDC, 0.2 A at 125 VDC, and 0.1 A at 250 VDC. The adjustable time range of 1 to 20 s covers common delay-on and delay-off sequences in motor start circuits, conveyor sequencing, and star-delta transitions — the part explicitly supports star-delta circuit wiring. The 5 A thermal current rating means the relay contacts handle sustained control-circuit loads without derating; the 24 VDC contact rating of 1 A is the limiting factor for DC inductive loads like contactor coils. Recovery time is 150 ms, so the relay resets fast enough for rapid cycling applications. The part has no ON-delay or OFF-delay function; it is a timing relay with adjustable time, not a delayed-action relay.","metaTitle":"Siemens 3RP1574-2NP30 SIRIUS Timing Relay, 200-240 VAC, 1-20","metaDescription":"Siemens 3RP1574-2NP30 SIRIUS timing relay. 200-240 V 50/60 Hz supply, adjustable 1-20 s delay, 5 A thermal current.
