ZN63A(VS1)-12 Indoor High Vacuum Circuit Breaker

The CLSR-12 series is a next-generation compact solid-insulated ring main unit (RMU) designed for high operational safety in power distribution networks. It serves as a core unit in distribution systems, featuring modular components such as circuit breakers with three-position disconnectors, load switches with three-position disconnectors, fuse modules, insulated busbars, and cable connectors.

ZN63(VS1)-12 type indoor high-voltage vacuum circuit breaker, a three-phase AC 50Hz rated voltage of 12kV power system indoor switching equipment, as the power grid equipment, industrial and mining enterprises power equipment protection and control unit. Suitable for frequent operation at rated operating current, or multi-alternating short-circuit current.

The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fi xed installation unit, and can also be equipped with a special propulsion mechanism to form a handcart unit.

LW36-126/3150-40 self-energized AC high-voltage sulfur hexafl uoride circuit breaker is an outdoor product, suitable for use in power grids with an altitude of no more than 2000 meters (products with an altitude of more than 3000 meters can be designed), an ambient temperature of not less than -40℃ , and a pollution level of no more than 50Hz in AC, with a maximum voltage of 126kV in the IV level area.

High-capacity TUR distribution board for 1000 kVA transformers. Dimensions 1450 x 900 x 540 mm, fixing centres 760 ± 20 mm horizontal and 590 mm vertical. It uses 4 x 240 mm² or 2 x 630 mm² per phase, and 2 x 240 mm² or 1 x 630 mm² for neutral. Upstream connection includes three U-shaped interphase brackets and six connection plates at 30 ± 5 Nm. The 1800 A handle is fixed with two M8x20 screws with captive washers.
