GUBA 

Threaded covers 

Flameproof, Exd, IIB or IIC, IP66 

Zone 1 


Application: 

GUBA threaded covers are used 

with GUBA boxes in control systems 

in hazardous areas 

Indoors and outdoors 

• In three categories: 

Flat - for normal use; furnished with 

standard GUBA boxes 

Glass window - to provide visibility 

of meter indications when used to 

enclose meters 

Dome - for increasing volume of 

GUBA to make it easier to splice and 

pull large conductors 

Features: 

• Dome - more suitable for use 

when splices of heavy conductors 

are made and enclosed, since the 

conductors may be pulled in with the 

ends outside the box. After the 

splices are made, they do not have 

to be crowded back into the box 

• Glass window - has maximum 

diameter glass to give best visibility. 

In selecting, the diameter of the 

meter face should match or be 

slightly smaller than window 

diameter. 

• Supplied with O-ring gaskets

Note 3: 

Limitations apply on terminal populations within Exe enclosures to ensure maximum power 

dissipation limits are not exceeded. Terminal populations can therefore increase where terminal loads are 

less than the maximum rated. Consult factory for details. 

The maximum number of terminals outlined for instrumentation circuit currents are recommended as 

a practical limit to ensure generous wiring space is available. Larger quantities of terminals can be provided. 

Large power terminal - Available on request, consult factory.
