This part of ISO10924 specifies miniature circuit breakers with tabs (blade-type), Form CB11 for use in road vehicles. It establishes, for this circuit breaker form, the rated current, test procedures, performance requirements and dimensions.
This part of ISO10924 is intended to be used in conjunction with ISO10924-1 and with ISO10924-2. The numbering of its clauses corresponds to that of ISO10924-1 whose requirements are applicable, except where modified by requirements particular to this part of ISO10924.
This part of ISO10924 is applicable to circuit breakers with a rated voltage of 14V and/or 28V, a current rating of≤30A and a breaking capacity of 2000A intended for use in road vehicles with a nominal voltage of 12V and/or 24V.
The circuit breakers are different in dimensions and functions, such as electrically reset, automatic reset, manual reset, and switchable.
NOTE This type of circuit breaker is intended to be used in similar applications as miniature fuse-links according to ISO8820-3. While the tab dimensions and current ratings can be the same, there might be differences in performance which the user of these products is advised to consider.
