It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously.
Double pole breaker symbol.
It cannot be used to supply 240 volts to a single circuit.
This switch can be wired up as a reversing switch for a motor.
Circuit breakers come in several styles including the standard single pole breakers that serve 120 volt household circuits and double pole breakers that take up two slots in a breaker box and serve 240 volt appliances a special kind of circuit breaker is the tandem breaker which is designed to allow two 120 volt circuits to be fit into a single slot in the circuit breaker box.
Dpst double pole single throw.
This switch can be wired up as a.
A different type of doubled up breaker is a quad breaker which serves two 240 volt circuits but is the same width as a standard double pole breaker.

Such kind of breakers is used in three phase systems in industries.
Double pole breakers have two hot wires that are connected by a single neutral wire.
This symbol represents circuit breaker with three poles.
Unlike a double pole breaker which serves a single 240 volt circuit a cheater serves two 120 volt circuits.
