Medium Voltage Vacuum Contactors
A medium-voltage vacuum contactor is an electrically operated contactor whose main power contacts make and break a specified load circuit inside evacuated interrupters.
Product & engineering
Understand the product.
This report studies the Medium Voltage Vacuum Contactors market, Vacuum contactors utilize vacuum bottle encapsulated contacts to suppress the arc. This arc suppression allows the contacts to be much smaller and use less space than air break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used fairly extensively in dirty applications, such as mining. Vacuum contactors are also widely used at medium voltages from 1000-5000 volts, effectively displacing oil-filled circuit breakers in many applications.
Vacuum contactors are only applicable for use in AC systems. The AC arc generated upon opening of the contacts will self-extinguish at the zero-crossing of the current waveform, with the vacuum preventing a re-strike of the arc across the open contacts. Vacuum contactors are therefore very efficient at disrupting the energy of an electric arc and are used when relatively fast switching is required, as the maximum break time is determined by the periodicity of the AC waveform. In the case of 60HZ power (United States standard), the power will discontinue within 1/120 or 0.008333 of a second.
Each power pole contains a vacuum interrupter with fixed and moving contacts, a sealed enclosure and an insulated mechanical operating connection. External terminals connect the pole to the circuit. In a multi-pole design, levers, drawbars or a common carrier transmit actuator motion to the poles. The assembly also provides contact pressure, return or selected latching mechanisms, auxiliary switches and the required separation between medium-voltage conductors and the low-voltage drive.
On the manufacturer's AC load duty, opening the contacts establishes an arc within the interrupter until interruption around a current zero, after which the gap must recover dielectric strength. The actuator's movement time and any electronic command delay are separate from the arc-interruption event. Drive designs can use an initial closing pulse followed by reduced holding current, or selected mechanical latching and release arrangements. An AC or DC control supply identifies the coil interface, not an interchangeable AC/DC rating for the main power circuit.
A motor starter can combine the contactor with overload protection and coordinated current-limiting fuses. The contactor performs operations within its own making and interrupting limits; a high fault beyond those limits must be addressed by the approved protective arrangement. Vacuum switching can also produce transients associated with current chopping and the connected load. Load impedance, cable and motor characteristics, surge provisions and operating frequency belong in the assembly review rather than being dismissed by a general claim about vacuum interruption.
What turns activity into demand
Assess the load cycle and interruption limits alongside the starter's fuse, relay and control design before selecting the contactor. This is the vacuum contactor component or specified contactor unit, not a vacuum circuit breaker with a different protective duty. A complete motor starter also includes enclosure, isolation, protection and control elements as offered. The report's voltage categories are retained; a single manufacturer's range does not define every medium-voltage contactor's rating.
