PEPI Bimetal Thermal Fuses

ATC Semitec’s range of ‘single-shot’ bimetal thermal fuses or cut-offs from PEPI offer superior and reliable thermal protection particularly at high temperatures, especially above 200°C where pellet fuses can often be less reliable. They have the benefit of offering a wider range of temperatures between the points of opening and closure.

Ceramic versions are also available offering settings up to 280°C.

These high temperature thermal fuses from PEPI (Portage Electric Products Inc) use unique bimetal technology which stops them from resetting, even at temperatures as low as -35°C. They do not suffer from thermal ageing like eutectic fuses, so can be more closely coupled to the appliance or heater providing fast accurate protection.

These fuses are highly versatile in how they can be tailored to meet your individual application- including operating temperature ranges, lead lengths, added terminals, insulting sleeves etc.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.
