Siemens SIRIUS 3RT1926-2CG21 is a two-wire solid-state timing relay that mounts on Siemens 3RT contactors (sizes S0–S3) to add a precise on-delay in control circuits. It provides an adjustable on-delay from 0.5 seconds to 10 seconds and operates from a 24 to 66 V, AC or DC control supply, with a varistor across the supply for surge suppression. This accessory is designed for compact integration with compatible contactors to generate timed enable signals in motor control or automation applications where a short startup delay is desired.
