Spare parts Webasto Overheat Fuse ZSB Stretched

Details

The Webasto Overheat Melt Fuse (Article Number: 406287) is a critical genuine safety component designed for Webasto DBW series coolant heaters, including the DBW 2010, DBW 2020, DBW 300, DBW 350, and Scholastic models. This specialized fuse acts as a vital failsafe measure, engineered to permanently interrupt the electrical circuit if the heater reaches a potentially dangerous temperature of 138 degrees Celsius (280 degrees Fahrenheit). Identified by its distinct yellow wax indicator, this melt fuse is essential for protecting the heating unit and the vehicle from safety-critical consequences resulting from cooling system failures, such as a failing water pump, air locks, or obstructions in the coolant circuit. It is a non-sensoric component intended for one-time use; once the thermal threshold is exceeded and the fuse "blows," it must be replaced to restore heater operation. This part is also known under interchange part numbers 1319406A and VHD1319406A. EAN: 4054037003790
