Siemens 3RT1926-2GC51 Solid-State Time-Delayed Auxiliary Switch, 100-127V AC, Star-Delta Function For Sizes S6-S12 Original Brand New

Overview

The Siemens 3RT1926-2GC51 is a high-performance solid-state time-delayed auxiliary switch engineered for precision and reliability in motor control systems. Designed for easy front-mounting, this auxiliary switch features a time range of 1.5 to 30 seconds, supports 100–127 V AC voltage, and includes 2 normally open (2NO) contacts. Tailored specifically for star-delta (wye-delta) starting functions, it is compatible with Siemens contactor sizes S6 through S12.

This unit is ideal for integration in automated control panels, motor starters, and other industrial applications requiring timed switching functions.

Key Benefit

• Reliable Timing Control: Provides precise, programmable time-delay switching from 1.5 to 30 seconds.

• Easy Installation: Front snap-on mounting design simplifies setup and maintenance.

• Compact & Durable: Built to Siemens’ exacting industrial standards for long-term operation.

• Versatile Voltage Support: Operates at 100–127 V AC, making it suitable for a wide range of systems.

• Optimized for Motor Starters: Designed for use with S6 to S12 size Siemens contactors in star-delta applications.

Function & Application

• Star-Delta Starting (Wye-Delta Function): Ensures smooth motor start-up by timing the transition between star and delta connection.

• 2 Normally Open (2NO) Contacts: Ideal for control logic where auxiliary signaling or actuation is required after a delay.

• Control Panel Integration: Perfect for OEMs, panel builders, and automation engineers requiring reliable auxiliary timing control.
