This Product Guide describes the withdrawable vacuum circuit breakers manufactured by Tavrida Electric.
Tavrida Electric circuit breakers are designed for rated voltages up to 24 kV.
Withdrawable vacuum circuit breakers are designed for indoor installation in air-insulated switchgear panels and
are intended to perform switching operations in network rated and faulty modes.
The breakers consist of the following main components:
• Indoor Switching Module (ISM) - The air-insulated ISM incorporates Tavrida Electric vacuum interrupters
incorporated in solid dielectric insulator controlled by per phase monostable magnetic actuators. No SF-6 or oil
insulation is used in the ISM.
• Control Module (CM) - The CM is a microprocessor-based controller that provides ISM operation,
protection and data logging functions.
This guide contains information about the circuit breaker‘s technical parameters, functionality and operating
principles. The purpose of the document is to provide necessary product information for application engineers and
technical personnel utilizing the equipment.
