YARV-20С
Distributive boxes of electric energy
of the YARV-20С series
Power boxes with cut-in switches and fuses are designed to protect networks and receivers of electrical energy from unacceptable long-term overloads and short-circuit currents, infrequent (up to 6 per hour) switching circuits of active and inductive loads.
