What is the difference between SPN & DP MCB?

Question

Accepted Answer

SPN and DP MCB are types of circuit breakers used in electrical systems.

SPN MCB stands for Single Pole Neutral Miniature Circuit Breaker, while DP MCB stands for Double Pole Miniature Circuit Breaker.
SPN MCB is used for single-phase electrical systems, while DP MCB is used for three-phase electrical systems.
SPN MCB has one pole and can interrupt the current flow in the live wire, while DP MCB has two poles and can interrupt the current flow in both the live and neutral wires.
SPN MCB is commonly used in residential and small commercial applications, while DP MCB is used in larger commercial and industrial applications.
SPN MCB typically has a lower current rating compared to DP MCB.
For example, a 20A SPN MCB can handle a maximum current of 20A, while a 20A DP MCB can handle a maximum current of 40A (20A per pole).
