VACUUM CIRCUIT BREAKER PRODUCT GUIDE

This Product Guide describes the Vacuum Circuit Breakers manufactured by Tavrida Electric. Tavrida Electric circuit breakers are designed for rated voltages up to 24 kV. Vacuum Circuit Breakers described in the current document can be used in various kinds of switchgear and RMUs and are intended to perform switching operations in network rated and faulty modes. The breakers are comprised of following main components: Indoor Switching Module (ISM) - The air insulated ISM incorporates Tavrida Electric vacuum interrupters with monostable magnetic actuators and solid dielectric insulating...

1.2 Definitions Closing time The closing time is the time period from the moment the close command is applied to the CM to the time when all ISM poles make contact. Opening time The opening time is the time period from the moment the trip command is applied to the CM to the time when all ISM poles are separated. Break time The break time is the time period from the moment the trip command is applied to the CM to the time when the arcs in all phases are extinguished. 1.3 Disclaimers Tavrida Electric will not accept any claims for damages caused by improper transport, storage as well as...

2.1 Product application field The circuit breaker is usually installed in radial or loop cable distribution systems. The main applications are: • Switching different types of load in normal and fault modes; • Isolating faults in the cable network. Due to their short closing and opening times (see Table 15), 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...
