The Siemens 3RT1926-2FJ31 is a SIRIUS auxiliary switch with an adjustable ON-delay that can be set between 5 and 100 s. It is designed for control circuits that need a delayed signal after the operating coil is energized — common in star-delta transitions, sequential start delays, or ventilation interlocks. Rated for a maximum of 3 A, with 1 A at 24 V DC. Recovery time is 150 ms; minimum ON period is 200 ms.
