Shields illuminating type OPV
Shields illuminating type OPV intended for reception and distribution of electric power lines and protection from overloads and short-circuit currents in the lighting network AC frequency of 50 Hz at a nominal voltage of 380/220 V and for infrequent operations on and off electric circuits.
Shields are installed in industrial, public and office buildings, and are mounted on the vertical surfaces of building structures or built into a niche.
Dimensions niches for mounting flaps (LhVhN) mm 360h180h260 - shields for OPV-6 360h180h410 - shields for OPV-12.
As the input apparatuses apply automatic or non-automatic circuit breakers and RCD.
circuit breakers (in accordance with the ordering customer), fuses, circuit breakers are used to protect branch circuits lines.
The design of the flaps enables replacement devices installed in the panel without removing the panel and provides an opportunity to service devices and contact connections from the front side.
Behind the door panel is operational panel connected on the devices it controls, eliminating access to live parts when the door is open.
Dimensions shields are shown in Figures 1-4.
electrical circuit diagrams are shown in Figures 5-12.
