Leading you to an educated decision.
These are non-renewable fuses which are current-limiting and intended for the protection of components sensitive to short-time overloads and short-circuit protection of motor circuits.
Class CC fuses must be labeled %u201CCurrent Limiting,%u201D and may be labeled %u201CTime Delay.%u201D The optional time-delay test requirements for this class of fuses is different than that of other larger body fuses.
Class CC fuses are the most current limiting, rating for rating, as compared to other types of control power fuses, that%u2019s what makes them particularly suited for use in IEC devices.
As more specs and end-users are requiring Type 2 protection levels for both NEMA and IEC devices, they%u2019re also using CC current-limiting fuses to satisfy this requirement.
