CBk 19" cabinet compatible with EMC standard

Description:

CBk cabinet is a CB cabinet adapted for 19" equipment that requires electromagnetic protection (EMC). It's manufactured in 24 standard sizes, a combination of six heights, two widths, and two depths. The standard cabinet consists of a welded frame, front door, two side panels, rear panel, roof, four mounting profiles, grounding strip, a set of grounding cables and four leveling feet. Castors or plinth can be ordered as supplementary accessories. The frame's top plate is solid, whereas the bottom plate has a 380 x 380 mm (15" x 15") opening that enables cable entry through the cable channel, which is situated in the room's floor. The blanking plate can cover the opening. Upon request the blanking plate can also be fitted with copper gland seals. The cabinet interior is equipped with four mounting profiles for 19" equipment mounting. The profiles can be fixed at the necessary depth with defined pitch. The 800 mm (31.5") wide cabinet has mounting profiles fixed on special outriggers. Extra spaces between profiles and side panels can be used for leading cable, or any other application on customer's request. Side and rear panels are fixed with screws to the cabinet's frame. Doors are fitted with a rod-latch lock. Both door and side panels, as well as the bottom plate's blanking plate, are galvanic joined to the cabinet frame through the application of special electroconductive gaskets. These cabinets can't be bayed in a row because of the door overhang.
