Enclosures
MTE enclosures are designed to provide a degree of protection for electrical components and
prevent incidental personnel contact with the enclosed equipment. Depending on the enclosure
selected, these enclosures meet the requirements of NEMA 1, 2 or 3R.
An approximate cross reference guide between NEMA, UL, CSA and IEC enclosure follows.
Type 1 NEMA / IEC IP20 Enclosure:
Are designed for indoor use and will provide protection against contact with the enclosed
equipment.
Type 2 NEMA / IEC IP20 Enclosure:
Are designed for indoor use and will provide protection against contact with the enclosed
equipment and provide a degree of protection against limited amounts of falling water
and dirt.
Type 3R NEMA / IEC IP21 Enclosure:
Are designed for outdoor use primarily to provide protection against contact with the
enclosed equipment and provide a degree of protection against falling rain sleet and
external ice formation.
Agency Approvals
UL and cUL listed to UL508 Type MX and CSA-C22.2 No 14-95
File E180243
Warranty
Three years from the date of shipment. See www.mtecorp.com for details.
Over Temperature Switch
Table 4-2: Over Temperature Switch
MTE highly recommends the use of the over temperature switch to prevent damage to the filter
in rare instances of overheating from abnormal operating conditions.
