Product Description

Product Description
    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 monstable magnetic actuators and solid dielectric insulating materials. 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;
 · Kits - The kits of components are used to provide circuit breaker application properties.
   This guide contains information about the circuit breaker 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.
