SERIES RTKB IEC Ex (Simtars Australia)

RTKB – 2 RTKB – 1

Features include

•Very high impact resistant glass fiber reinforced Thermoplastic – Polyamide

•Good chemical resistance: see data

•Degree of protection IP66

•Easy fit fixing tabs – (speed up installation and cut down frustration) designed for unistrut, ideal for flat bar, angle irons up to 80mm wide plus large flat surfaces

•3 or 5 entry options – easy to install and easy to terminate

•Enclosure labeling system

SPECIAL NOTE: To minimize the risk of electrostatic discharge, enclosures should not be fitted where they can be subjected to high flow of powder dust that may lead to a prolific charge build up being generated, e.g. pneumatic transfer of powder of discharge spraying. Reference IEC 60079.0:2011 clause 7.4.2. The lid shall have the following warning label applied.

WARNING

Do not open when energized

Potential electrostatic charging hazard

Note: All cable glands and blanking elements e.g. stopping plugs, are separately certified Ex e Ex t as applicable with an ingress protection level of IP66 if fitted as per the manufacturer’s instructions.
