Single Pole MCB is for 120V and Double pole is for 240 V. Single pole controls 1 live wire and Double pole can control 2 live wires.
For an example, a refrigerator is connected to your power supply of 230 V (Rated) by means of Double pole MCB. If any one of the live wire gets short circuited, the other one which is connected to MCB also gets tripped with that. In other case, if you connect two single pole circuits, and if one live wire gets short circuited, it will be a dangerous.

Difference between TP and TPN isolator?
The main difference between the two is that a TP isolator is only a "triple pole" isolator. A TPN isolator is a "triple pole" and neutral isolator.
What is difference between spn and tpn mcb db?
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.
What is the difference between a tpn mccb and a 4 pole mccb?
The difference between a tpn mccb and a 4 pole mccb is rather negligible. The only real difference is that a 4 pole mccb works a little bit faster and allows for a strong network connection. The connection with a 4 pole mccb is just a bit more reliable.
Describe a double pole single throw relay with a 24 V coil And how does it work?
Double pole single throw relay de-energized, with two separate sets of contacts open. Apply 24 volts to coil terminals, coil steel core magnetizes and pulls hinged armature towards it. The two contacts attached to hinged armature make contact with the two stationary contacts. The double pole relay has now two separate sets of closed contacts.
What is meant by SPDT?
In electronics, an SPDT is a type of switch. It stands for "Single Pole, Double Throw." In America, it's known as a three-way switch.
What is the difference between a single pole switch and a double pole switch?
A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
What is the difference between a single pole and a double pole breaker?
A single pole breaker controls one hot wire and is used for 120-volt circuits, while a double pole breaker controls two hot wires and is used for 240-volt circuits.
What is the difference between iron clad double pole switch and double pole single throw switch?
Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment. A double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.
What are the differences between a single pole and a double pole breaker?
A single pole breaker controls one wire and is used for 120-volt circuits, while a double pole breaker controls two wires and is used for 240-volt circuits.
Double pole or single pole hot water heater thermostat?
Single pole.
What are the differences between a single pole and a double pole light switch?
A single pole light switch controls one light fixture from one location, while a double pole light switch controls one light fixture from two locations.
What are the differences between a single pole light switch and a double pole light switch?
A single pole light switch controls one circuit and has one switch, while a double pole light switch controls two circuits and has two switches.
What are the differences between a double pole and a single pole breaker?
A double pole breaker controls two hot wires and provides 240 volts of power, while a single pole breaker controls one hot wire and provides 120 volts of power.
What is difference between single pole and double pole switch?
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.
What does dp and sp mean on a socket?
Double pole and single pole.
What is the difference between single pole and double pole thermostats?
A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.
How does a double pole light switch differ from a single pole light switch in terms of functionality and wiring?
A double pole light switch controls two separate circuits, while a single pole light switch controls only one. Double pole switches have four terminals for wiring, while single pole switches have two.
