The KARI LS90 thermal fuse is a reliable safety device for applications in which high temperatures may cause serious damage to the equipment or constitute a fire hazard. A typical application is a heating station using oil as its energy source, where the KARI LS90 is installed in the vicinity of the oil burner. When the temperature exceeds 90 °C, the metal alloy in the fuse box melts, which results in the power being cut off. Oil supply to the station is interrupted, leading to an alarm being raised. Based on a set melting temperature, the KARI LS90 is an extremely reliable safety device without any electric sensors susceptible to disturbances or complex electronics.
An excellent choice for a circuit breaker and alarm system in a range of applications
The KARI LS90 is an excellent choice for a safety and protective device in the vast majority of applications in which the temperature must not rise above 90 °C. It can be used as a simple alarm system or alternatively as a circuit breaker in a device, which, if overheated, may cause serious damage to the equipment or constitute a fire risk. Such a hazardous situation may, for example, arise as a result of a fault in an oil burner’s thermostat, causing problems in the control of oil supply and overheating of the oil burner.
An ideal safety solution for heating systems
The KARI LS90 offers a reliable safety solution for small and large systems alike. In addition to oil-fired power stations and houses with oil heating, it is suitable for other heating methods, including systems using natural gas or pellets.
