Ex118BSS Range | 11,000 Volts | 800 Amp | Flameproof Couplers

Rated for 800 amps with an operating voltage of 11,000 volts, the Ex118BSS has benefited from AusProof’s drive to continuously improve and innovate.

Ex-certified and with a rating of IP66, the Ex118BSS is suitable for use underground operational sites, and pumps and tunnelling projects, though this coupler can also be used in metalliferous sites if a higher level of durability is required. Each component of the Ex118BSS has been researched by AusProof’s Research and Development team to ensure that all parts work together to create a high quality, reliable and safe product. The design of the Ex118BSS allows for this coupler to have its gland tensioned at any time, without the need to remove components. It is also more resistant to damage on its flameproof paths.
