Product details

Varistor surge suppressor for SIRIUS S0 contactors

The Siemens 3RT6926-1BD00 is a varistor-type surge suppressor designed for the SIRIUS S0 contactor frame size. It clips directly onto the contactor to suppress voltage transients across the coil, protecting the control circuit from inductive kickback during de-energisation.

Dimensions are 12 mm depth, 30 mm width, and 19 mm height. Suitable for installation in standard control cabinets without derating for ambient heat up to 60 °C.

Sourced through independent distribution channels. No stock-holding claim; quoted to order per RFQ.
