Product Positioning

The Siemens 3RT2926-1MR00 is a diode surge absorber specifically designed for Size S0 contactors in the 3RT20 series. Rated at DC 24V, it is directly attached to the A1/A2 terminals of the contactor coil to absorb induced surges during coil de-energization, reducing interference to surrounding control circuits. This model also features a built-in LED indicator for easy visual confirmation of the coil's energization status by field personnel.

Core Product Advantages and Features
Diode surge absorber
The suppression element adopts a diode design to absorb the induced surge generated when the coil is de-energized.
Dedicated Size S0 contactor
Applicable to the coil terminals of 3RT20 series Size S0 contactors; the correct model must be selected.
Rated voltage DC 24V
The corresponding coil rated voltage is DC 24V, and the selected model must be consistent with the contactor coil voltage.
LED action indicator
Built-in LED indicator light allows for immediate visual confirmation of the coil's energization status.
