It provides power to 3 conductors simultaneously, and more importantly, disconnects all three conductors simultaneously in case of a fault. A three pole breaker is used with a three phase power system.

can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
3 pole circuit breakers are used for 3 phase lines
No, you cannot use one in place of the other.
is there an error if the upstream circuit breaker is 16A TP and the downstream circuit breaker is 16A TPN?
Yes, the rating of a 3 pole circuit breaker is the same for each conductor that is connected to it. A three pole breaker rated at 30 amps will have 3 #10 wires from it that connect to the load.
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
A 2 pole breaker is a type of circuit breaker that controls two separate electrical circuits simultaneously. It is commonly used in applications where a higher voltage or larger electrical load is required. The 2 pole breaker functions by opening the circuit when an overload or short circuit occurs, thereby protecting the electrical system from damage.

A double pole breaker is a type of circuit breaker that controls two separate electrical circuits at the same time. It differs from a single pole breaker in that it can disconnect both the hot and neutral wires in a circuit, providing greater protection against overloads and short circuits. This makes it suitable for larger appliances or circuits that require more power.
The purpose of a 50 amp 2 pole breaker in an electrical circuit is to protect the circuit from overloading by disconnecting the power when the current exceeds 50 amps.
No, a 2 pole breaker is designed for a 240-volt circuit or for two separate 120-volt circuits that are out of phase with each other. For a 120-volt single-phase circuit, you would typically use a single-pole breaker.
TPN means three pole with one pole neutral connected.
The appropriate double pole 30 amp breaker to use for a dryer installation is a 30 amp double pole circuit breaker.
The purpose of a 30 amp double pole breaker in an electrical circuit is to protect the circuit from overloading by shutting off the power if the current exceeds 30 amps.
The purpose of a 50 amp single pole breaker in an electrical circuit is to protect the circuit from overloading by interrupting the flow of electricity if the current exceeds 50 amps.
