PVR-33-11-20-UHL3 Circuit Breaker-Fuse Switch for Electrical Protection

Current-limiting fuses-switch-disconnectors-series PVR-33 100 A - 440 V, - 220 V PVR apparatuses combine the functions of two apparatuses - switch-disconnectors with arc-quenching chambers and fuses. The use of devices of series TAC in switchgears gives essential economy of working space of switchgears, reduces quantity of electric connections and used current-carrying parts. The main advantage of TAC in comparison with automatic machines is switching off of short-circuit currents by fuses, because switching capacity of fuses is always much higher than that of automatic machines. TAC devices are completed with fuses of PPN series.
