Over 50 years of experience.

Originally founded and incorporated as Multi-State Devices Ltd. to design and market a unique type of NTC thermistor with avalanche characteristics, now known as the Moxie, the company lacked the resources necessary to flourish and was subsequently sold. Since the acquisition by Microtherm GmbH in 1978, the entire Microtherm thermostat line was taken on and promoted. After several years of distributing the Microtherm thermostats manufactured in Germany, CANTHERM now produces a wide variety of snap-action, temperature limiting, bimetallic thermostats according to Microtherm designs for a wide variety of applications. Devices are available for the thermal protection of electric motors and transformers, medical devices, temperature sensitive electronics, power supplies, or anywhere that heat could become a problem.
