DC coil suppression for S0 contactors
The 3RT6926-1ES00 is a SIRIUS surge suppressor with a diode combination, sized for S0 frame contactors. It clips onto the contactor to suppress the inductive kickback from a DC control circuit. Rated for DC control supply voltages from 30 to 250 V, it protects the PLC output or relay contact driving the coil from voltage spikes during de-energisation.
DIN-rail footprint and mounting
The suppressor measures 12 mm deep, 30 mm wide, and 19 mm high — it adds negligible width to the contactor stack on the DIN rail. Clip-on fastening and any mounting position simplify panel layout.
