VACUUM CIRCUIT BREAKER
630A/1250A/1600A/2000A/2500A/3150A/4000A
12kV/24kV/35kV

ZN63(VS1) The series vacuum circuit breaker is crafted for a rated voltage isolator ranging from 12kV to 35kV, featuring a robust 3-phase switch device, ideal for indoor usage as grid equipment, in industrial and mining enterprises, ensuring seamless power equipment control and unmatched protection unit. Thanks to its unique advantages, these vacuum circuit breaker products are perfectly suited for current demands requiring frequent operations, or multiple open short-circuit current scenarios. With an integrated layout structure, this breaker uses a sophisticated spring operation mechanism that is mature, boasting a simple structure and exceptionally reliable performance. The well-thought-out construction ensures clarity at each point, offering functional units to aid in hassle-free maintenance.
The ZN63(VS1) vacuum circuit breaker can seamlessly be installed within the switch either as a fixed unit, or as a drawn-out form. With a current rating that spans from 630A to 4000A and supports a rated current rating from 20KA to 31.5KAshort-circuit current,it presents a fully serialized form.

Core Features
Vacuum Arc Extinguishing Technology
Utilizing a high-performance vacuum arc extinguishing chamber, this breaker showcases strong breaking capabilities, with no risk of explosion, making it environmentally friendly and completely pollution-free.

Its rated short-circuit breaking current effortlessly reaches 20kA to 31.5kA (depending on the model).

Modular Design
The spring energy storage operating mechanism offers rapid opening and closing speeds, coupled with a mechanical lifespan ranging from 10000 to 30000 cycles.

This unit can be equipped with manual or electric control options (supporting remote automated operation).

Safety Protection
Boasting a fully enclosed insulation structure with a protection level of IP3X, it is both dustproof and moisture-proof.

Designed with an integrated mechanical interlocking system, our product ensures the highest level of safety by effectively preventing any potential misoperation.

Standards
Our product proudly meets and exceeds stringent international and domestic standards, including: GB/T 1984 and IEC 62271-100.
