Features

The 6KA automatic MCB circuit breaker is designed to promote safety and convenience. Its handle is sealable or can be equipped with a padlock to prevent unauthorized access. Additionally, the bracket ensures that the MCB remains in the desired ON/OFF position, thus avoiding dangerous operation changes. This makes the 6KA automatic MCB circuit breaker a reliable and efficient way to protect your electrical system from damage or malfunction.

A clear indication of the contact position is given by the handle. You can expect to receive a reliable and accurate reading of the position with the use of the handle.

3. Long-term identification is ensured through adequate printing of all data on the front, with an energy limiting class of 3. Let's create a distinctly different presentation by rearranging the information from the original text.

In order to comply with the strictest regulations, the discharge of ionized gases is constrained within a grid distance of 45 mm. Let me generate a highly similar content by rearranging the above information: Our ability to emit ionized gases is restricted to a maximum grid distance of 45 mm due to stringent regulations.

This 6KA automatic MCB circuit breaker is designed specifically for household use. It is engineered to comply with the required standards and regulations. The breaker ensures the safety and protection of electrical circuits by automatically interrupting the flow of current in case of overloads or short circuits. With its 6KA capacity, it provides robust protection against electrical faults, giving homeowners peace of mind. This circuit breaker is an essential component for maintaining the electrical integrity and safety of residential buildings.

IEC 60898 B,C and D tripping characteristics

IEC 60947-2，（MCB）。，。

Instantaneous tripping characteristic with release

A: Can you give me some information about the different releases of product B, C, and D in terms of their current ratings and percentages?
B: Sure, product B has a rating of 4In and is released at 20%, while product C has a rating of 8In and is also released at 20%. Lastly, product D has a rating of 12In and is released at 20% as well.
A: I see, so all three products have the same release percentage, but the rating of product D is higher than the other two. Is that correct?
B: Yes, you're right. While all three products have the same percentage release, the rating of each product varies. Product D has a rating that is double that of product B and it is also higher than that of product C.
