Product Description

Product Description

T-avrida Electric MD Circuit Breakers are designed for rated voltages up to 15 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.

• Kits - The kits of components are used to provide Withdrawable Vacuum Circuit Breakers application properties.
