DC0438 Digital Thermatic® Fan Switch, 1/4" NPT Sensor & 38mm Adapter Kit

This kit is designed to manage your Electric Fans or Electric Water Pump (EWP^®) with professional precision. It features a 38mm inline adapter for easy integration directly into the engine's top radiator hose, alongside two thermal sensors for versatile installation options.

The switch handles 1 or 2 fans and is compatible with 12V or 24V applications (24V requires DC10534 relays). With dual-fan logic, Fan 1 starts at the set temperature, and Fan 2 activates 10 seconds later, ensuring your electrical system isn't overloaded during startup.
