Siemens 3RT1926-2GJ51 Solid-State Time-Delayed Auxiliary Switch for Star-Delta Function, 24V AC/DC, 2 NO, Sizes S6-S12 Original Brand New

Overview

The Siemens 3RT1926-2GJ51 is a high-performance, solid-state time-delayed auxiliary switch designed for seamless integration with Siemens contactors, specifically those of sizes S6 through S12. This front-mountable module is engineered to simplify complex motor control applications, particularly star-delta (wye-delta) starting. Featuring a precise, adjustable time delay ranging from 1.5 to 30 seconds and a versatile 24 V AC/DC control voltage, the 3RT1926-2GJ51 ensures reliable and efficient motor transitions.

Key Features & Function

• Solid-State Technology: Provides enhanced durability, longer operational life, and superior switching reliability compared to traditional electromechanical timers.
• Star-Delta (Wye-Delta) Function: Specifically configured to manage the time-critical transition between the star (wye) and delta motor windings, reducing inrush current and protecting the motor and power system.
• Adjustable Time Range: The time delay can be precisely set from 1.5 to 30 seconds, allowing for fine-tuning to meet specific motor acceleration requirements.
• Versatile Voltage Compatibility: Operates on a wide 24 V AC/DC control voltage, making it compatible with a variety of industrial control systems and power supplies.
• Front Snapon Mounting: Designed for quick and easy installation directly onto the front of Siemens contactors (Sizes S6-S12), saving panel space and simplifying wiring.
• 2 NO (Normally Open) Contacts: Features two normally open auxiliary contacts to provide feedback and control signals within the motor starter circuit.

Benefit

• Improved System Efficiency: Optimizes the motor starting process, leading to reduced energy consumption and lower operational costs.
• Enhanced Motor Protection: Minimizes mechanical and electrical stress on the motor by controlling the transition from star to delta configuration, extending motor lifespan.
