Product Positioning

The 3RT1926-2GJ51 is a time-delay auxiliary contact module specifically designed for star-delta (Y-Δ) step-down starting circuits. It can be directly installed on Siemens SIRIUS 3RT10 series large contactors, providing time delay control functionality. The module contains one set of normally open contacts with delayed action and one set with instantaneous action, facilitating the switching timing requirements of star-delta starter groups.

Core Product Advantages and Features

Star-delta dedicated design

Optimizes star-delta step-down start-up circuits, providing a combination of delayed and instantaneous dual contacts.

1 delay + 1 instantaneous normally open contact

Two sets of normally open contacts correspond to delayed and instantaneous actions respectively, satisfying the switching logic requirements.

Delay range: 1.5~30 seconds

The delay time can be adjusted according to the motor's starting characteristics to adapt to different starting loads.

24V AC/DC control voltage

It is compatible with AC and DC 24V control circuits and has high wiring flexibility.

Multi-size compatibility

Applicable to various 3RT10 contactor sizes such as S0, S2, S3, S6, S10, and S12.
