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 protection and overload protection during general load startup, and is suitable for instrumentation, low current signals, and protection circuits.
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.
