Note:-The manufacturer of panel shall submit a copy of type test report by CPRI that panel is made out of thermoplastic Polycarbonate in accordance with IEC 60439-1 and IEC 61439-2 for power switchgear and control gear assembly. For better safety the Polycarbonate enclosure shall be fire retardant & self extinguishing in accordance with IEC 60 695-2-1, DIN VDE 0304 Part 3, UL Subject 94 for Flammability V-2. It should be tested at Glow Wire test for 960 deg. Cent. The impact strength of polycarbonate enclosures / boards i.e. the Degree of Protection against Mechanical load shall be in accordance with EN 50298-98 for IK 08. Panel should have consisted of dew guard which is a passive solution for mitigation of condensation. The function of Dew Guard is to absorb moisture during high humidity and releases moisture during low humidity. This process ensures that a constant level of humidity is maintained in the enclosed space, due to which the product continues to be in function over a large period of time and protects against condensation. It absorbs moisture without any saturation, even in high humidity and maintain the humidity level in the panel.
