VS1 offers versatile
applications
Epoxy resin insulation cylinder manufactured with APG process can withstand severe environmental impacts, enabling VS1 breakers to be used in all kinds of situations.
The utilization of special contact material and primary tulip contact ensures VS1 devices applicable for all medium voltage cases.
Ambient air temperature is not exceeding 40ºC, and the average temperature measured within 24 hours is not exceeding 35ºCThe minimum ambient air temperature is -15ºC
Negligible effect by solar radiation
Altitude is not exceeding 1000m
Ambient air is not obviously polluted by dust, smoke, corrosive and flammable gases, vapor or salt mist
Negligible vibration or quake external to the switchgear and controlgrear
Amplitude of electromagnetisminterference sensed in secondary system is not exceeding 1.61kV
Average daily relative humidity: 95%; average monthly relative humidity: 90%
Average daily vapor pressure: 2.2*10-3MPa,Average monthly vapor pressure: 1.8*10-3MPa
No water dropping, flammable and explosive hazards in the application places, without chemical corrosive gases and violent vibrations.

VS1 completely meets
demands of power users
VS1 series vacuum circuit breaker offers drawout type VS1 and fixed type VS1, based on different operation environments, applied separately for centrally installed switchgears and fixed type switchgears, to satisfy different requirements from users for different application occasions
Drawout type VS1 breakers have been widely used in all kinds of centrally installed switchgears. Due to its reliable interlocking and stable performance, it can be applied within most of centrally
installed switchgears. In the places where old generation switchgears are used, Eaton’s fixed type VS1 breaker can still achieve mechanical interlocking* function with dedicated mechanical interlocking mechanism to coordinate with the old generation switchgear.
VS1 series vacuum circuit breaker also offers solutions of all rated currents, to fully meet demands of electrical users.
* Customers are required to provide relevant switchgear information for customization.

VS1 Vacuum Circuit Breaker
First class vacuum interrupters are utilized for the breaker, with reasonable price but superior performance
Adoption of multi-point compressing contact method, lowering contact resistance and extending breaker’s service life and without maintenance
The insulation tension pole used for the breaker must be subject to force measurement, ensuring contact pressure in closing state, and can be traceable
Technology creates
history
Eaton has over 80years manufacture experience of circuit breakers. Over the past 80years, we are leading global circuit breaker market with the most advanced technology and concept.
In the world advocating environment conservation, the expectation for medium voltage power switching is very high. Along with lower impedance system configuration, the demand for current continuity and breaking capacity is higher; meanwhile the demand for installation in limited spaces and cooling is more stringent. The optimal solution is our medium voltage circuit breakers with advantages of pro-environment, reliably breaking heavy-duty current, without extra cooling or forced air cooling.
VS1 vacuum circuit
breaker requires almost
no relevant maitenance
Simple structure design of Eaton’s VS1 vacuum circuit breaker minimizes fault occurrence, and simplifies daily maintenance.
