This circuit breaker is rated as 12V-48V 100A and I have to use this circuit breaker between additional alternator (24V 100A) in my vehicle and additional battery bank to provide overcurrent/short circuit protection. Will it be efficient to my 24V system or is not recommended using a 48V circuit breaker to protect my 24V system.

The voltage rating of a circuit breaker or fuse is the maximum circuit voltage at which the performance will be as specified. The higher the operating voltage the farther the contacts must open to break the arc when a breaker opens from an overload. So a 48 volt (maximum) circuit breaker will have a good safe margin in a 24 volt system.
