Medium Voltage three-phase circuit breaker designed for pole-mounted or substation applications up to 12 kV, 630 A, 20 kA.
These circuit breakers are of live tank or dead tank design, pole mounted switching devices for smart grid applications, providing protection and control for overhead distribution lines. They are also flexible to receive various relays and voltage inputs besides a wide auxiliary and control voltage range - 24V, 48V, 110V, 220V.
PVB : Three phase, 12 kV, 630-1250 A, 20kA, solid dielectric insulator, environmental free with remarkable high vacuum technology and HCEP (Hydrophobic Cycloaliphatic Epoxy) solid dielectric insulation.
PVB-S : three phase, 12 kV, 630A, 25kA, vaccum interrupter inside of SF6 insulation environment to prolong product life.
