NB3LEU-63 circuit breaker, mainly used for AC 50Hz /60Hz, rated voltage
AC 400V/415V (while working normally within the voltage range from 340V
to 457 V), rated current 10A to 63A, overload, short circuit and leakage
protection of electrical lines and equipment, can also be used as
infrequent connection and disconnection of the line.

• Complies with IEC/EN 61009-1 safety standard for RCBOs. Ensures the device provides reliable protection against electric shock, overload and short circuits, and meets strict performance and safety requirements for electrical safety.
• Type A class Trip on both AC and pulsing DC leakage currents, whether they rise quickly or slowly, ensuring reliable protection for modern electrical loads. 
• A D-curve is designed to tolerate high inrush currents and trips only when the current reaches about 10 to 20 times the rated current instantly (magnetic trip). It also provides standard thermal protection for overloads. 
• Mounting: DIN rail EN 60715 (35mm) by means of a fast clip device
