SHORT ANSWER
The correct electrical product cannot be selected by looking at just one value.
The product group, rated current, number of poles, breaking capacity, protection function, load characteristics, panel conditions and accessory compatibility should be evaluated together.
This center connects product selectors, comparisons, and verified explanations to enable users and search systems to clearly understand the technical subject.

Frequently searched electrical terms.
Definitions are for pre-selection; project calculation and the manufacturer's current technical documentation should be used as a basis.
- What is MCB?
- Modular miniature circuit breaker; used for overload and short circuit protection.
- What is MCCB?
- It is a compact circuit breaker; it is used in distribution circuits requiring higher current and breaking capacity.
- What is RCCB?
- Detects residual current and opens the circuit; provides no inherent overload and short circuit protection.
- What is RCBO?
- Residual current, overload and short circuit protection are combined in one device.
- What are Icu and Ics?
- The breaking capacity of the compact circuit breaker expresses its final and service short-circuit breaking capacity.
- What is IΔn?
- The rated residual operating current of the residual current device is not the same value as the rated current of the device.
- What is number of poles?
- The device specifies the number of conductors it can switch simultaneously; 1P, 2P, 3P, 4P and neutral options are evaluated separately.
- What is breaking capacity?
- The short-circuit current that the protective device can safely interrupt under specified conditions, expressed in kA.
