Core Product Advantages and Features
C-type instantaneous break-out characteristics
With a trip current of approximately 5 to 10 times the rated current, it meets the requirements for surge and overload protection during general load startup, making it suitable for high-current power circuits and air conditioning units.
25kA high breaking capacity
According to IEC/EN 60898-1 standard, the rated short-circuit breaking capacity is 25kA (230/400V), and it can withstand large fault current surges.
2-pole circuit breaker design
Both poles disconnect simultaneously, and both poles operate in unison, making it suitable for simultaneous disconnection of the line and the neutral/secondary pole, thus improving maintenance safety.
DIN rail quick installation
The standard 35mm DIN rail snap-fit design allows for tool-free quick installation and replacement, shortening the construction and maintenance time of the distribution box.
