Product Q&A

Q:What are the rated voltage and current specifications?

The rated voltage covers 12kV and 24kV, while the rated current ranges from 630A to 4000A.

Q:How does the vacuum circuit breaker extinguish arcs?

It uses vacuum as the extinguishing medium, which has no conductive medium, allowing for extremely strong extinguishing ability and rapid insulation recovery.

Q:What are the differences between spring and permanent magnet mechanisms?

Spring mechanisms are mainstream with 30,000-60,000 cycles, while permanent magnet mechanisms offer over 100,000 cycles, lower power consumption, and stronger anti-vibration ability.

Q:Can the installation be customized for different spaces?

Yes, it supports handcart type for flexible switching and maintenance, or fixed type for compact, low-frequency scenarios.

Q:What customization services are available?

We offer full customization, minor customization, and customization based on designs or samples.
