STAHL 133104 Ex i Junction Boxes Installation Guide

STAHL 133104 Ex i Junction Boxes

MODEL: 8118/211-403
Art. No:  133104

• Resistant Ex e enclosure, universally usable as connection or junction boxes and/ or to safeguard electric distributors up to 6.3 A
• IP66 degree of protection
• With mantle terminals or with a combination of mantle terminals and miniature fuses (optional)

WebCode 8118A

R. STAHL Series 8118 junction boxes are equipped with 4, 5 or 8 mantle terminals depending on their design size. As an option, miniature fuses can still be installed in addition. Junction boxes are therefore also suitable for safeguarding. The robust enclosure made from glass fibre reinforced polyester resin can be equipped with plastic or metal cable glands.
