Complectation

Vacuum circuit breakers EM/VL are intended for installation in switchgears (both high-voltage and medium voltage) of industrial enterprises, large buildings, power plants, and are designed to protect equipment and personnel in cases of earth fault, short circuit or in case of the occurrence of overload current. Vacuum switch (6-10 kV to 40.5 kV) is equipped with an arc chute which opens the circuit after the signal from the relay which is located separately from the switch.

EM/VL switches are characterized by a reliable compact design, high breaking capacity (up to 50 kA), high rated current (up to 4000 A) and availability of various accessories.

Vacuum circuit breakers of EM/VL brand have the increased reliability due to optimized temperature characteristics. The design of devices fully complies with all safety requirements put forward for this type of devices.
