I have never seen a four pole circuit breaker. Breakers are single, two and three pole. Single pole for 120 volts, two pole for 240 volts and three pole for three phase loads. In North America all neutrals are SN (solid neutrals) and are not switched.
In certain applications using a three phase Y-connected load, where complete isolation of the load from the supply is required, the neutral line connects to one pole of a 4 pole circuit breaker.
What else can I help you with?
What is mean by 4 pole ELMCB?
A 4 pole ELMCB refers to a 4-pole Earth Leakage Miniature Circuit Breaker. It is a type of circuit breaker that trips when it detects a leakage current to ground, protecting against electric shocks or fire hazards. The 4 poles indicate that the ELMCB provides protection for all phases and the neutral wire in a circuit.
Can you use a 2 pole breaker for a 120 volt single phase circuit?
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.
How do you define a pole in circuit breaker?
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.

What is mean by 4 pole ELMCB?
A 4 pole ELMCB refers to a 4-pole Earth Leakage Miniature Circuit Breaker. It is a type of circuit breaker that trips when it detects a leakage current to ground, protecting against electric shocks or fire hazards. The 4 poles indicate that the ELMCB provides protection for all phases and the neutral wire in a circuit.
What is a 2 pole breaker and how does it function in an electrical circuit?
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.
Where is the double-pole circuit breaker located?
before the load
What circuit breaker will interchange with American Switch Company?
Replacement for American Switch single pole 15 amp circuit breaker
What is a double pole breaker and how does it differ from a single pole breaker in terms of electrical circuit protection?
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.
What is the purpose of a 4 pole breaker in an electrical circuit and how does it differ from other types of breakers?
A 4 pole breaker in an electrical circuit is used to disconnect power from all four wires in a three-phase system simultaneously. This differs from other types of breakers, like single pole or double pole breakers, which only disconnect power from one or two wires respectively.
What is the purpose of a 50 amp 2 pole breaker in an electrical circuit?
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.
Can you use a 2 pole breaker for a 120 volt single phase circuit?
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.
What is air circuit breaker?
TPN means three pole with one pole neutral connected.
What is the purpose of a 30 amp double pole breaker in an electrical 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.
What is the purpose of a 50 amp single pole breaker in an electrical circuit?
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.
What is the appropriate double pole 30 amp breaker to use for a dryer installation?
The appropriate double pole 30 amp breaker to use for a dryer installation is a 30 amp double pole circuit breaker.
