Summary of Contents for ABB AMVAC
- Page 1 AMVAC Vacuum Circuit Breaker with Magnetic Actuator Mechanism...
- Page 2 AMVAC circuit breakers have been fully tested to the most recent versions of ANSI C37.04, C37.06, and C37.09. Using "k" factor equals 1 as the test criteria, the AMVAC is the first ANSI medium voltage circuit breaker to successfully complete standard and definite purpose capacitor switching tests as described in the revised standards.
- Page 3 The AMVAC is truly the next generation in medium voltage vacuum technology. With the AMVAC, ABB is the first to combine the unique requirements of vacuum interrupter technology to a stored energy mechanism designed to exploit these capabilities. Using a flux-shifting device with integral permanent magnets, the AMVAC mechanism has just one moving part.
- Page 4 Electronic controller unlock the circuit breaker from the breaker compartment. Magnetic actuator The AMVAC circuit breaker is Electrical energy storage designed to provide many years of trouble free service for the end Sensor for switching position detection user.
- Page 5 AMVAC. Qualities that convince. Maintenance free vacuum interrupter and current carrying parts in one embedded assembly. 27 kV 15 kV 5 kV Innovation extends to the vacuum interrupter assembly, as well. For the first time in any vacuum circuit breaker, the interrupter and the current carrying parts are completely embedded in a proprietary epoxy resin.
- Page 6 All operating mechanism functions are integrated in the magnetic actuator of the AMVAC circuit breaker. The actuator is a bi-stable magnet system, in which armature change-of-state is Magnetic latching in a accomplished by the magnetic field of two limit position.
- Page 7 AMVAC. Circuit-breaker of the high tech generation. The electronic controller uses robust components and circuit board con- forming coatings to prolong the life of the device. The electronic con- troller will operate on AC or DC control power because it utilizes an AC to DC converter internally.

- Page 9 AMVAC. The modern circuit breaker. The AMVAC is the first vacuum circuit breaker to combine low maintenance embedded vacuum interrupters, a low maintenance magnetic actuator, and a maintenance-free electronic controller. The result is a medium voltage circuit breaker capable of 100,000 operations.
- Page 10 AMVAC. Circuit breaker specifier's guide. General The Circuit breaker shall be an ABB AMVAC or approved equal, three-pole, drawout (or stationary) type, electrically operated with stored energy magnetic actuator operating mechanism. The circuit breaker is intended for use as a...
- Page 11 On drawout circuit breakers, a self-aligning, fully automatic secondary coupling system shall be used to connect and disconnect all control wiring during circuit breaker insertion and withdrawal. The secondary disconnect shall require no manual intervention to attain proper position when the breaker is racked to the “Connected”, “Test”, or “Disconnected”...
