Scope
In comparison to conventional circuit breakers, the Tavrida Electric vacuum circuit breakers is comprised of two
components:
· The ISM (Figure 1)
· The CM for controlling the ISM (Figure 2)
Both modules must only be operated together and are meant for indoor installations only. The possibility to choose
the ISM and CM separately allows any type of switchgear to be easily equipped with regard to its primary and
auxiliary circuits.
This guide contains information on the operation, installation, commissioning and testing of the Tavrida
ISM_LD series of breaker products.
