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

ZN63(VS1) This series vacuum circuit breaker is highly sought after for its excellence as a rated voltage isolator spanning the range of 12kV to 35kV, making it an exceptional 3-phase switch devicefor indoor environments as trusted grid equipment, ideal for industrial and mining enterprises, providing unmatched power equipment control and robust protection unit. Thanks to its special advantages, our vacuum circuit breaker products meet the stringent requirements for rated current in high-frequency operations, or multiple instances of opening short-circuit currents. With its integral layout structure, the breakers utilize a mature spring operation mechanism, highlighting a simple structure and ensuring reliable performance. The thoughtfully planned construction makes all functional points clear, ensuring functional units are easy to maintain and service.
The ZN63(VS1) vacuum circuit breaker can be installed within the switch as a fixedunit, or it can be drawn. With a capacity ranging from 630A to 4000A and rated current ratings from 20kA to 31.5kAfor short-circuit current, it offers real serialized form adaptability.

Core Features
Cutting-edge Vacuum Arc Extinguishing Technology
This breakthrough technology employs a high-performance vacuum arc extinguishing chamber, boasting strong breaking capabilities, without any explosion risks, making it environmentally friendly and completely pollution-free.

The rated short-circuit breaking current can remarkably reach 20kA to 31.5kA (contingent upon the model in use).

Innovative Modular Design
The spring energy storage operating mechanism guarantees swift opening and closing speeds, with a mechanical lifespan extending from 10,000 up to a notable 30,000 cycles.

Flexibility is further augmented as it can be equipped with either manual or electric control systems (fully supporting remote automation operations).

Unmatched Safety Protection
Boasting a fully enclosed insulation structure, it achieves a protection level of IP3X, ensuring it's both dustproof and moisture-proof.

Additionally, it incorporates built-in mechanical interlocking to safeguard against misoperations.

Standards
Impeccably Compliant with Prestigious International and Domestic Standards, Including: GB/T 1984 and IEC 62271-100.
