THERMAL FUSE LS 90

The KARI LS90 thermal fuse is a reliable safety and protection device for applications where a rise in temperature could cause serious equipment damage and fire hazards. A typical example is an oil burner system, where the KARI LS90 is installed near the oil burner. If the temperature rises above 90 degrees Celsius, the alloy inside the fuse melts and interrupts the electrical current, stopping the oil supply and triggering an alarm. The KARI LS90 is an extremely reliable safety device because its operation is based on melting temperature without any vulnerable electrical sensors or complex electronics.
