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, supercompact 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.

The DC-voltage converters developed for the electronic components in the motor car are characterised by their ease of installation in every vehicle. The high degree of stability, the compact design, sustained short-circuit resistance as well as the high level of operating safety are the quality hallmarks of this series. The areas of application span the mobile employment of 12-V-consumers in vehicles with a 24-V-onboard network. The devices are particularly suitable for operating car radios, stereo units, radios, cooler units, car telephones, computers, 12-V-trailer lighting etc. The voltage converter converts an input direct voltage into an output direct voltage. The input voltage must be greater than the output voltage. No base load is required at the output end. A 26 kHz PWM switching controller is used for this purpose. Input and output are not isolated. The common earth is connected with the voltage converter housing.
