COMAT RIC20-xxx-SR Installation Contactor — 2 Pole 20A DC Coil with TVS Suppressor

A slim, silent-operation installation contactor for railway-approved power switching applications, fitted with a DC-only control coil and an integrated bidirectional TVS surge suppressor. The RIC20-SR fits a single DIN rail module width, making it well suited to space-constrained panel builds in rolling stock and rail infrastructure environments, including HVAC, door control, lighting and signalisation circuits.

Rated at 20A with DC control voltage, the RIC20-SR is available in twelve variants across four coil voltages and three contact configurations — select your combination below.

ComatReleco products are designed and tested against EN 50155 (railway rolling stock electronic equipment) and EN 45545-2 (fire protection). Compared to standard industrial contactors, the range is built with V0 fire-rated housing material, wider coil tolerances suited to rail supply conditions, and moisture-protected PCB coatings.
