The features of the Indoor Vacuum Circuit Breaker.

Core protection mechanism

It achieves rapid circuit breaking through the built-in vacuum interrupter, effectively isolating circuit faults and preventing safety accidents caused by overload or short circuit. Its design draws on the "weak link" concept of fuses, actively disconnecting the circuit to avoid equipment damage.

High reliability and durability

Utilizing vacuum insulation technology, it boasts excellent insulation performance and arc resistance capabilities, with a long service life.

Wide application scope

Mainly used for indoor high-voltage circuit protection, such as 12kV/24kV AC circuits. Models include ZN65-12, VN63A, etc., suitable for lighting, power and other scenarios, balancing safety and practicality.

Intelligent and modular design

Some models support intelligent monitoring and modular configuration, which can provide real-time feedback on circuit status and achieve rapid maintenance and upgrades through standardized interfaces. For example, the American standard model (such as Zn63A-Vs1) adopts a modular design to enhance system compatibility.
