Product details

0.05–100 s, single-function ON-delay

The 3RP1525-1BW30 is a SIRIUS ON-delay timer with an adjustable time range of 0.05... 100 s, set by a single front-panel scale spanning 0.8 to 1.1 of the selected range end — a hard set-and-forget function with no pulse-shaping or star-delta modes on this code. Recovery time is 150 ms, which sets the minimum cycle between successive timing starts.

24–240 V AC/DC coil, any DIN-rail position

Coil supply accepts 24... 240 V across DC and 50/60 Hz AC — a single part covers control transformers from a 24 VDC cabinet bus up to a 230 VAC control circuit, which removes the stocking headache of separate 24 VDC and 120/230 VAC timer SKUs. Housing footprint is 22.5 mm wide × 91 mm deep × 102 mm tall — a standard 22.5 mm DIN module, panel-friendly for retrofit alongside SIRIUS 3RT contactors and 3RV motor protectors. Termination accepts 20... 14 AWG solid or stranded.

Panel-environment envelope

Operating temperature is -25... +60 °C; storage and transport widen to -40... +85 °C — fine for an unheated cabinet in winter and a non-condensing enclosure near a process skid. Pollution degree 3 with basic insulation, so it sits alongside other control gear in a typical industrial panel without extra creep/clearance margin.

Frequently asked questions

What is the 3RP1525-1BW30 listed depth on the SIRIUS Time Delay Relays line?

Depth is 91 mm, with a width of 22.5 mm and a height of 102 mm — the standard 22.5 mm DIN module footprint that drops into the same cut-out as adjacent SIRIUS control gear.
