Notes for MTL Systems:
Enclosures include barrier mounting hardware, tagging strips, etc. Labeled wiring
ducts are included with MT 32.
Listed enclosures are glass-filled polycarbonate with transparent lids. They are
impact resistant, flame retardant and dustproof to IEC529:IP65.
MTL will install barriers at no charge if supplied with position (sequence) information.
"Internals" (everything that normally goes in an enclosure but no enclosure) are
available.
