2.1 Product Application Field
The circuit breaker is usually installed in radial or loop cable or overhead distribution systems. The main
applications are:
• Switching different types of load in normal and fault modes.
• Isolating faults in the cable or overhead network.
Due to their short closing and opening times (see “Technical Parameters” on page 23), Tavrida Electric circuit
breakers can bring significant benefits to the following applications:
• Arc flash protection;
• Automatic backfeed restoration.
2.2 Key Benefits
Tavrida Electric circuit breakers provide the following competitive advantages:
• Environmentally friendly
The ISM does not use SF-6 insulation materials.
The CM and ISM modules are manufactured from environmentally friendly materials.
• Lightweight
The total weight of the withdrawable vacuum circuit breakers with a rated current of 1250 A and a CM does
not exceed 88 kg, making it the most lightweight indoor circuit breaker on the market. The total weight of
the withdrawable vacuum circuit breakers with a rated current of 3150 A and a CM does not exceed 165 kg,
making it the most lightweight indoor circuit breaker on the market.
• High reliability
30,000 CO operations at rated current and 50 full rated short-circuit operations without any maintenance
make it the most reliable circuit breaker on the market.
• Fastest operation time
The withdrawable circuit breakers described in this product guide are based on Tavrida Electric ISMs, which
provide extremely fast operation timing and can be successfully utilized for such demanding applications as
fast transfer switch, fast internal arc clearance and other applications.
• High operator safety
The open design of the draw-out unit provides visual control of its main circuit‘s disconnection when it is in
the test position.
In case of auxiliary supply loss, manual charging of the circuit breaker is performed by connecting to the CM
in the low voltage compartment, excluding the necessity of operating inside the high-voltage compartment.
2.3 Compliance
Tavrida Electric withdrawable vacuum circuit breakers have been tested by world-renowned testing laboratories. A
list of test reports is presented in “Appendix 1. Type Tests”.
