The delay is set via a pneumatic mechanism with an adjustable pickup delay time of 10 to 180 seconds, providing a timed interval between coil energisation and the switching of the delayed contacts. ## Contact Configuration and Wiring The block provides one normally-open (NO) and one normally-closed (NC) delayed-switching contact, giving a single-pole changeover function on a timed basis. Connection to the auxiliary and control circuit is via screw-type terminals, a standard termination method for panel wiring that accepts ferruled or solid conductors. For short-circuit protection of the auxiliary switch, the manufacturer specifies a gG 10 A fuse rated for an assumed short-circuit current of 1 kA per IEC 60947-5-1 — this must be included in the branch circuit feeding the timer block. ## Sourcing and Lifecycle Sourced and quoted to order against a BOM quantity — availability and current pricing confirmed at the time of RFQ.","metaTitle":"Siemens 3RT5926-2PA11 Pneumatic Time-Relay Block","metaDescription":"Siemens 3RT5926-2PA11 pneumatic time-relay block, on-delay 10-180 s, 1NO+1NC contacts for 3RT5 contactors size S2-S3.
