FAQ
1、What are the wiring methods for this model?
There are 4 types in total: Front panel wiring,rear panel extended wiring,plug-in front panel wiring,plug-in rear panel wiring.
2、What are the differences between thermal magnetic and electronic types?
The thermal-magnetic type is based on thermal/electromagnetic effects and is suitable for general protection; the electronic type provides more precise protection settings and more functions.
3、What protection functions does it have?
Overload protection, short circuit protection, undervoltage protection.
4、What is breaking capacity?
The maximum short-circuit current that the MCCB can safely cut off, in kA. The selection should be greater than or equal to the fault current value.
