Fireproof junction boxes IP55 from stainless steel

Installation boxes fireproof KM-O IP55 are designed to connect and branch fireproof cable lines. 

The body is made of stainless steel sheet AISI 304 1.2 mm thick. Fireproof junction box body has a rectangular or square shape. The lid is hermetically sealed to the housing by the connection with screws and sealing silicone gasket. 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. 

Fireproof junction boxes KM-O IP55 are made of stainless steel grade AISI 304, which has chemical and corrosion resistance, high strength, and has excellent low-temperature properties. All external fixing elements are made of stainless steel.  There are special seal sleeves installed in side walls providing not less than IP55 degree of protection.

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.
