This would typically be seen in older residential installations where the service was of such a high amperage that the mains required larger breakers than were available (for that panel). Placing two breakers in parallel allowing sharing of the load. Two breakers per (split) phase would total four breakers.
Two breakers of 50 amp rating each (in parallel) provide (generally) 100 amps of protection. Two sets of two would provide mains protection for a 200 amp service.

Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
Circuit breakers are used for the same purposes as?
