PTC Resettable Devices, Radial Lead Overcurrent Protection – PTR Series

Eaton Bussmann’s PolyTron™ polymeric positive temperature coefficient (PPTC) devices protect sensitive components

Image of Eaton Bussmann's PTC Resettable Devices, Radial Lead Overcurrent Protection – PTR SeriesEaton Bussmann's PolyTron PTC family of radial-leaded resettable fuses are based on a special positive coefficient material whose internal resistance increases exponentially in response to overcurrent conditions and higher temperatures. They are designed to protect sensitive components from overcurrent and overtemperature conditions that can occur due to power surges, electrical transients, high ambient temperatures, and more. Eaton’s resettable PTC fuses ensure constant uptime in applications where using one-time fuses would be impractical or expensive, such as battery-powered devices, industrial controllers, medical devices, and I/O ports of consumer electronics.
