Sounds like a 240 volt sub panel feeding a well pump.
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.
Tandem breakers, often called split breakers or double breakers, provide two separate circuits in the space of a regular sized breaker opening. Every circuit breaker panel has a limited number of circuit openings available. The problem is that when the openings are all used up and you still need to add another circuit, what do you do? You could change the electrical panel or double up circuits on a breaker, but this could place too much load on a particular circuit. So what then? The answer that many have found is a tandem breaker. This type breaker is the same size as any other breaker, but it has its difference. This breaker sports two smaller breakers built into one regular sized breaker. Each has its own breaker switch and the breaker snaps in just like a regular breaker. With this simple innovation, you can add a circuit and protect the circuit on its own dedicated line.
A double 15 amp breaker is used in an electrical circuit to provide protection against overloading and short circuits by allowing two separate circuits to be connected to a single breaker. This helps prevent damage to the electrical system and reduces the risk of electrical fires.
A circuit breaker with 2 switches typically refers to a double-pole circuit breaker. This type of circuit breaker has two separate switches that simultaneously disconnect both the positive and negative wires of a circuit, providing complete electrical isolation. It is commonly used for appliances or devices that require a dedicated electrical connection.
A double lug breaker is used to connect two separate electrical circuits to a single breaker. It functions by allowing both circuits to be controlled by the same breaker, providing a convenient way to manage multiple circuits with limited space in an electrical panel.
A 50 amp double breaker in an electrical circuit is used to protect the circuit from overloading by disconnecting power when the current exceeds 50 amps.
A double lugged breaker in an electrical circuit is used to provide additional connection points for wires, allowing for increased electrical capacity and distribution within the circuit.

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.
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
A double pole 60 amp breaker in an electrical circuit is used to protect the circuit from overloading and short circuits by disconnecting power when the current exceeds 60 amps.
The appropriate double pole 30 amp breaker to use for a dryer installation is a 30 amp double pole circuit breaker.
