Hazardous Location

Meltric DXN Hazardous Location plug and receptacle

Protection for Most Gas and Dust Environments

MELTRIC offers a wide range of Hazardous Location products that provide connection solutions for most installations in gaseous and dusty environments.  With Zone 1 & 2, Zone 21 & 22 and Class 1 and Class 2, Division 2 products available, they cover any environment other than those with an almost continuous presence of the hazard. 

 

Models are available with cCSAus certifications from 20A to 250A in 3 phase devices and up to 600A in single pole devices. ATEX and IECEx configurations are available from 20A to 125A in 3 phase devices and up to 680A in single pole. 

Some are compact and lightweight yet very durable poly devices, others are larger robust metal devices and all feature spring-loaded butt contacts and either silver-nickel or silver contact surfaces to provide consistently superior electrical performance and long operating lives.

The protection methods, ratings and certifications vary by product line. See the range summaries and features descriptions below or click here for a comparison table showing all the ranges.
