The enclosures GUB and GUBW are normally installed in the industrial
plants, with potential hazardous atmospheres of gases and combustible
dusts, and therefore classified as Zone 1 – 2 – 21 – 22.
These enclosures are primarily used with the function of:
• Cable termination unions, with terminals for derivation or change section
cables.
• Protection of electric circuits, with automatic thermo-magnetic circuit
breaker (MCB or MCCB) and earth leakage device.
• Protection of electric circuits, with On-Load wsitches.
• components as fuse holders, ballast, transformers etc. etc.
