    en.wikipedia.org/wiki/Circuit_breaker

    Two-pole common-trip breakers are common on 120/240-volt systems where 240 volt loads (including major appliances or further distribution boards) span the two live wires. Three-pole common-trip breakers are typically used to supply three-phase power to powerful motors or further distribution boards.
