PEPI Bimetal Thermal Fuses

The PEPI H series of ‘single-shot’ bimetal thermal fuses from ATC Semitec offers the ultimate in thermal protection.  One-time, non-resettable bimetal thermal cut-offs (sometimes known as TCOs) are significantly more reliable than pellet-style fuses, particularly at high temperatures above 200°C.  These bimetallic fuses do not suffer from thermal ageing like eutectic solder or organic pellet fuses and can switch electrical loads as high as 15A/250VAC at temperatures up to 280°C.

These high temperature thermal fuses from PEPI (Portage Electric Products Inc) use a unique bimetal technology which stops them from auto-resetting, even at temperatures as low as -35°C. Bimetal thermal fuses can be more closely coupled to heater operating temperatures thus providing much faster over-temperature protection and improving product safety.

These thermal fuses are highly versatile and can be customised to meet your application; operating temperature, terminal types and/or lead-wires are available to match your application.  Used widely in office automation, small appliances, 3D printers, hair-stylers, industrial heaters, etc.

Improve your next appliance design by using a bimetallic thermal fuse instead of a pellet fuse.
