Siemens SIRIUS 3RT1926-2EC31 Solid-State Time-Delayed Auxiliary Switch, ON Delay, 5-100s, 100-127V AC, 1NO+1NC Original Brand New

Overview

The Siemens SIRIUS 3RT1926-2EC31 is a high-performance, solid-state time-delayed auxiliary switch block designed for seamless integration with SIRIUS 3RT1 contactors (sizes S6 to S12, or S0-S3 as indicated by some sources, so referencing the broader range for compatibility is safe). This electronic, front-side snap-on module provides crucial time-delay functionality in control circuits, specifically utilizing the ON-delay (slow-operating) principle.

It features a versatile time range of 5 to 100 seconds and operates on a control supply voltage of 100 to 127 V AC (50/60 Hz). Equipped with 1 Normally Open (NO) and 1 Normally Closed (NC) contact, the 3RT1926-2EC31 ensures reliable, time-controlled switching operations, enhancing the functionality and safety of industrial automation systems. Its compact, front-mounting design simplifies installation and saves valuable space in control cabinets.
