Yes, our parts have been RoHS Compliant since February 2006. RoHS certification can be found here.
Please see NEMA ratings chart below. UL & NEMA Ratings are based on independent lab testing by UL and/or information available from the manufacturer.
All of Polycase enclosures can be rated IP40, assuming the covers are properly secured. We have several series meeting higher IP ratings per the below chart. Most Polycase IP Ratings are based on the NEMA 250 to IEC 60529 conversion table published by NEMA.org. NEMA Enclosure Types exceed the requirements for the respective IEC 60529 designation. IEC 60529 specifies that an enclosure designated with the stated degree of protection indicated by the first characteristic numeral (IPXX) also complies with all lower degrees of protection. An enclosure designated with a degree of protection indicated by the second characteristic numeral (IPXX) also complies with all lower degrees of protection up to and including the second characteristic numeral 6. An enclosure designated with a second characteristic numeral 7 or 8 is not suitable for water jets (5 or 6) unless it was tested for water jets and is dual coded.
