The Tavrida Electric VCB series contain the most unique design elements of any MV breaker on the market.

All components are assembled along a single axis, with mono-stable magnetic actuator (one per pole). The actuators drive a pulling insulator that, in turn, connects to the advanced Tavrida vacuum interrupters at the top of the breaker.

In comparison with conventional circuit breaker that allowed to:

  • Reduce number of mechanical parts by 2-3 times.
  • Exclude gears, bearings, levers and other rotating parts prone to failure.
  • Achieve unique set of feautures and characteristics.


Tavrida Electric cooperates with more than 300 switchgear manufacturers and retrofit solutions providers worldwide.

Over many years of cooperation, Tavrida Electric VCBs have proved versatile and easy-to-use for both new and existing switchgear panel designs, as well as for retrofit solutions.

Tavrida Electric VCB series circuit breaker is so revolutionary — because its features allow you to design unique solutions.

    Low auxiliary power consumption
    Significant savings on auxiliary power supply and equipment ≤42 Watts during capacitors charging (max 7s).
    Continuous self-supervision
    Vacuum circuit breakers equipped with the CM16 control module continuously monitors control, switching modules, functional wiring and auxiliary power supply quality.
    Environmentally Friendly
    Tavrida's vacuum circuit breakers use SF6-free- and oil-free vacuum and solid insulation technology.


    Tavrida Electric has revolutionised circuit breaker design by developing a new generation of circuit breakers and controls with exceptionally fast opening, closing and response times.

    Fast Transfer Switcher

    With transfer times as fast as 2 cycles. Such quick operational times allow very sensitive loads to operate without interruption in the case of a main power source loss. The fast transfer switch solution:

    • Eliminates costly downtime
    • Reduces production equipment stress
    • Ensures quick return on investment
    Arc Flash Mitigation
    With interruption in one period. That quick interruption time:
    • Increases operational safety
    • Reduces switchgear restoration time and loss of productivity
    • Reduces costly downtime
    • Limits switchgear damage and repair costs
    Fault Current Limiter
    Sub period interruption time limits short circuit current effectively by quickly disconnecting distributed generation sources from the grid.
    • Allows more distributed generation, to be connected to the grid
    • Limits fault current
    • No operational losses
    • Enables automatic distributed generation sources reconnection


    Tavrida Electric's circuit breakers are the perfect match for applications like transformers or generators with a neutral earthing, server rooms and point on wave switching.
    Single Pole VCB Neutral Treatment Utilities
    • Starpoint treatment at generators Isolation, when using several generators in parallel.
    • Starpoint treatment at transformer for switching and bypassing transformers' neutral grounding devices like resistor, reactor, Peterson coil.
    Single Phase Load Switching
    Single phase vacuum circuit breaker could be implemented by various customers which have single phase loads, 4-wire distribution networks which have single phase loads to be operated independently:

    • Power utilities
    • Enterprises
    • Public buildings
    Controlled Switching
    Controlled switching is a technique of switching the electrical circuit on a specific point of a sin-wave – voltage or current, to minimize:

    • switching transients and associated inrush currents
    • voltage disturbances
    • re-strikes and arc re-ignitions

    Controlled switching main applications:

    • Mechanically switched capacitors (MSC)
    • Mechanically switched reactors (MSR)
    • Transformers
    • Hybrid STATCOMS
    • Power consuming drivers
    • Shunt reactors
      Starting and Braking Resistors
      Tavrida Electric vacuum circuit breakers are also applicable for starting and braking resistors switching and protection in:

      • Railway
      • Cranes
      • Conveyors
      • Mills


      Tavrida Electric manufactures small, compact vacuum interrupters with an extraordinarily long mechanical and electrical lifespan. A specially designed axial magnetic field distribution provides an even current density over the contact surface, substantially improving the vacuum interrupting performance.
      Vacuum interrupter contacts have unique design, based on the mixture of copper and chromium metals and various dopants, to ensure long electrical life of contacts, low contacts resistance and chopping current.
      The patented, super-compact actuator design allows the circuit breaker to be installed directly underneath each pole. The design is optimal in terms of reliability, dimensions, weight and ease of installation.
      A spring charged by the magnetic actuator during the closing of the circuit breaker ensures main contacts pressure is maintained. The spring is integrated in the actuator and does not require any maintenance during the circuit breaker's lifetime.
      Circuit breaker terminals are designed to reduce contact resistance and mitigate the risk of contacts overheating.
      The use of robot welded steel discs as opposed to folded bellows eliminates the main failure point of conventional circuit breaker designs and allows interrupter to do more than 150,000 CO cycles and contain high vacuum (10-6 Pa) for the entire lifetime.
      Tavrida Electric realized early on that the complexity and bulk of conventional operating mechanisms made them unreliable and reduced their lifespan. Every Tavrida Electric circuit breaker uses patented actuators designed and fabricated within our own facilities to drive the interrupter contacts. All switching elements of a pole are assembled along a single axis meaning all mechanical movements are direct and linear.


      Continuous Self-Supervision
      Vacuum circuit breakers equipped with the CM16 control module continuously monitors control, switching modules, functional wiring and auxiliary power supply quality. CM16 eliminates the necessity of additional trip and close coils, charging mechanisms and all related wiring supervision. The entire trip and close circuit supervision comes in single package with any Tavrida Electric VCB. CM16 allows the user to forget about scheduled trip and close wiring inspections - as in the event of malfunction corresponding notification will be sent to the operator using one of the inbuilt output relays and indicated by inbuilt in CM LEDs.
      Low Power Consumption
      Vacuum circuit breakers equipped with the CM16 control module need less than 42 W in charging mode – just 10% of what the best alternatives available on the market need! Such low power consumption finally solves the problem of auxiliary power supply – much less powerful source and UPS can now provide substation auxiliary equipment with required power.
      Ease of Use and Robustness
      CM16 type control modules are connected with the circuit breaker they control and supervise be means of simple wires. It allows the CM installation to be located at any position convenient for the OEM, system integrator or End-user location. Very compact dimensions and low weight further simplify the process. CM16 has a robust design, enclosed in an aluminium housing it provides high EMC level confirmed by KEMA test laboratories.
