CLASS C FUSES
Ferraz Shawmut Class C fuses have British standard
(BS88) dimensions and are exact replacements for
the British fuses and older HRCII-C fuses. Class
C fuses are not dimensionally or electrically
interchangeable with other North American fuses.
They feature ceramic bodies and bolt-in mounting.
They are for short-circuit protection only, in motor
controllers, for example, where overload protection
is provided by an overload relay.
* Ceramic version available upon request
