Description
The Siemens Industrial Controls 3RP2525-1AW30 On Delay Timer provides controlled time-delay switching for sequencing electrical operations. It regulates on a wide input range of 24/120V typically 12240V AC/DC, 50/60 Hz and features an adjustable timing range from approximately 0.05 seconds up to 100 hours, with a single changeover SPDT contact rated around 250 VAC at 3A for reliable switching within HVAC systems. Installed in control panels, air handling units, and automation circuits, it delays activation of connected components. As part of the control system, it supports proper sequencing, reduces electrical stress, and ensures stable operation.
