Installation boxes fireproof KM-O IP55 are designed to connect and branch fireproof cable lines. They are used for outdoor and indoor installation under a shelter.
Fireproof junction box KM-O IP55 body has a rectangular or square shape.
The body of junction boxes is made of 1,2mm thick galvanized steel and is covered by polymeric paint. It has double protection against corrosion because of galvanic treating and polymeric cover.
The lid is hermetically sealed to the housing by the connection with screws and sealing silicone gasket. Inside the enclosure there are ceramic terminal blocks. On the cover and on the housing there are grounding clamps "PE". The side walls are equipped with membrane-type sealing bushings, providing the degree of protection against penetration not lower than IP55.
The screw ends on the terminal block have a rounded shape that allows the wires to be secured without damage. Ceramic terminal blocks provide a secure connection in fire conditions. All external fixing elements are made of stainless steel.
The boxes are certified for compliance with the requirements of technical regulations: TR TS 004/2011 "On Safety of Low Voltage Equipment". TU 3449-005-70631050-2009.
