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.
