devices: 100 years of history

Eaton products can help safeguard virtually all

forms of electronic equipment and devices.

Eaton offers its Bussmann series one-time

fuses, fuse accessories, PTC resettable fuses,

and ESD suppressors in a broad range of

specifications for numerous applications.

Fuses

Almost every electronic device – from

portable and consumer devices to those

utilized in automotive, medical, and industrial

applications – requires some degree of

protection against overcurrent events. The

Eaton’s fuses serve two critical purposes:

they protect components, equipment, and

people from the risk of electric fire or shock

caused by damaging overcurrents;

they reliably isolate subsystems from the main

system once a fault has occurred.

PTC resettable fuses

Eaton Bussmann series Positive Temperature

Coefficient (PTC) resettable fuses are circuit

protection devices that provide overcurrent

Each PTC fuse consists of a positive

temperature coefficient material whose

internal resistance increases exponentially

with an increase in operating temperature.

Eaton PTC resettable fuses have two

functional states — ON and OFF. In the ON,

or “tripped” state, the device offers very

high resistance in response to faults such

as short-circuiting or overheating. This limits

current flow through the device until the

fault is removed and the material cools, then

Selecting Eaton

Bussmann series fuses

Eaton offers an extensive selection of fuses in

a variety of configurations. Selecting the most

suitable fuse for a specific application involves

considering a wide variety of parameters.

However, this catalog offers a simplified

approach for choosing Eaton Bussmann®

series fuses based on fuse type, technology,

and footprint.
