ZN85- 40.5 Indoor High Voltage Vacuum Circuit Breaker

Introducing the ZN85-40.5/T2000-31.5 Indoor High Voltage Vacuum Circuit Breaker (referred to as VCB), a cutting-edge solution tailored for 3-phase AC 50Hz power systems with a rated voltage of 40.5kV. Specifically designed to handle load currents, overload currents, and fault currents, this VCB is indispensable for mining enterprises, power plants, and substations.

This breaker boasts an innovative upper and lower layout for its operation structure, effectively reducing its depth. Ensuring a high level of safety, the 3-phase interrupter and associated live parts are isolated by three independent epoxy insulating tubes, forming a composite insulation structure. This configuration not only meets air distance and creepage distance requirements but also significantly minimizes the overall size of the VCB. The leading electric circuit interrupter, static and dynamic conductive connections are ingeniously housed within the insulating tube, reducing the phase distance to a mere 300mm. The fixed-type leading electric circuit enhances stability, and the insulating tube is expertly installed on the upside of the frame.

A specially designed spring actuator, seamlessly integrated into the frame, is a unique feature of this VCB. This design, tailored for the upper and lower structure, is an integral and inseparable part of the VCB. The overall design is simple, ensuring a more suitable output curve that aligns with the distinctive features and requirements of the 40.5kV VCB.

With a well-thought-out and aesthetically pleasing layout, this VCB stands out for its compact size, flexible endurance, ease of inspection, and maintenance-free operation. It is exceptionally suitable for frequent operations and can thrive in challenging environments, making it an ideal choice for locations with poor conditions. Embrace a circuit breaker that not only performs reliably but also embodies sophistication and practicality.
