Adjustable time spans 0.05 s... 100 h with a minimum ON period of 35 ms and a recovery time of 250 ms, which is wide enough to replace a stack of single-function timers (ON-delay, OFF-delay, pulse-delayed, pulse-shaping, additive ON-delay, star-delta) on the same DIN slot. ## Contact ratings in real circuits Two delayed-switching outputs give the wiring flexibility to run two independent time functions off the same timer, and the operating envelope of -25... +60 °C (with -40... +85 °C transport and storage) covers unheated cabinets and most outdoor enclosures. ## Lifecycle and panel-spare posture Lifecycle status is listed as current on the record, so the 3RP2505-1BW30 remains in normal production flow through Siemens' SIRIUS distribution channel. For a spare-parts strategy, the wide supply range and multifunction set mean a small on-hand quantity covers several replacement scenarios across a plant — one RFQ line replaces what would otherwise be a shelf of single-function timers.","metaTitle":"Siemens 3RP2505-1BW30 SIRIUS timer, 12-240 V, multifunction","metaDescription":"Siemens 3RP2505-1BW30 SIRIUS multifunction time delay relay, 12-240 V control supply, 5 A thermal current, DIN rail mount.
