It provides an adjustable OFF-delay function spanning 10 to 180 seconds, with one normally-open and one normally-closed delayed-switching contact each. The OFF-delay means that when the contactor coil is de-energized, the timer block holds the auxiliary contacts in their energized state for the set delay before releasing. This is the typical application for sequencing a fan run-down, conveyor brake release, or pump purge cycle after the main motor stops. This block mounts directly onto the front of a 3RT5 contactor frame S2 or S3, adding the time-delay auxiliary contacts without increasing the panel depth beyond the contactor's own profile. The auxiliary and control circuit connections use screw-type terminals, matching the contactor's own termination style. Per the datasheet, the short-circuit protection for the auxiliary switch requires a gG fuse rated 10 A at a prospective short-circuit current of 1 kA, in accordance with IEC 60947-5-1. This is a coordination requirement, not a continuous current rating — the auxiliary contacts themselves are rated for the usual 10 A AC-12 switching duty. The part carries a Substance Prohibitance compliance date of 05/01/2012, indicating it meets RoHS and similar restricted-substance requirements effective from that date. No further compliance documentation (UL, CSA, CE) is listed in the available spec record.","metaTitle":"Siemens 3RT5926-2PR11 Pneumatic Time-Relay Block, OFF-Delay","metaDescription":"Siemens SIRIUS 3RT5926-2PR11 pneumatic time-relay block, OFF-delay 10...180 s, 1NO+1NC, for 3RT5 contactors size S2-S3.
