It provides an adjustable pickup delay from 0.1 to 30 seconds with a stated relative accuracy of 20% of the set value, and switches one normally-open plus one normally-closed auxiliary contact. The block is rated for AC-12 duty at 10 A maximum, with voltage-dependent current ratings that drop as line voltage rises: 6 A at 230 V, 4 A at 400 V, 2.5 A at 500 V, and 1.5 A at 690 V. At 24 V it handles 4 A; at 48 V, 2 A; at 110 V, 0.7 A; at 220 V, 0.3 A; and at 440 V, only 0.1 A. These are the switching capacities for the auxiliary contacts under the respective voltages — the 10 A AC-12 figure is the thermal current limit for resistive loads. Mechanical service life is rated at 5,000,000 switching cycles typical when mounted on a 3RT2 contactor. The block is finger-safe (IP20 on the front), mounts in any position via clip-on fastening, and uses screw-type terminals. The block clips directly onto a size S0 contactor (3RT2 series) — no DIN rail footprint of its own. Overall dimensions are 45 mm wide, 44.6 mm high, and 83.5 mm deep.","metaTitle":"Siemens 3RT2926-2PA01-0MT0 SIRIUS Pneumatic Delay Block, S0,","metaDescription":"Siemens SIRIUS 3RT2926-2PA01-0MT0 pneumatic timing relay block, ON-delay 0.1-30s, 1NO+1NC, size S0, clip-on for 3RT2 contactors.

The SIRIUS contactor relays 3RH6140-1BF40 or 3RH6131-1BF40 offer auxiliary switching in a similar voltage/current range but are not pneumatic delay blocks — they lack the adjustable ON-delay (0.1-30 s) and the slow-operating design. If the delay function is not needed, those relays can switch similar loads; if the delay is required, this specific block has no drop-in substitute."},{"question":"Will 3RT2926-2PA01-0MT0 drop into a panel specified around 3RH6140-1BF40?","answer":"Not without rewiring. The 3RT2926-2PA01-0MT0 is a pneumatic delay block that clips onto a size S0 contactor (3RT2 series), while the 3RH6140-1BF40 is a size S00 contactor relay that mounts on DIN rail. The form factor, mounting method, and function are different — the delay block adds depth (83.5 mm) to the contactor stack, whereas the relay occupies its own DIN rail space. Panel layout and wiring would need to change."},{"question":"How do I get current pricing and availability for 3RT2926-2PA01-0MT0?","answer":"Submit an RFQ through this listing.
