Explosion proof terminal block
max. 95 mm² | Ex series
Terminal blocks and strips exposed to potential explosive environment need special approvals and are tested at a higher level than normal terminal blocks.
All terminal blocks used in hazardous environments %u201CEx e II%u201C have their type details printed on them. This information shows the Series No., the type of protection Ex e II, the approval No., the data approval and name of the test house.
All terminal blocks used in intrinsically safe current circuits %u201DEx i%u201C have their item nos.
Applications and advantages
Hazardous environments are areas in which the atmosphere may become explosive. Explosive atmosphere is defined as a mixture of ignitable substances in the form of gases, vapours or mixtures with air under atmospheric conditions in critically mixed ratios such that excessive high temperature, arcs or sparks may cause an explosion.
Such hazardous environment can form, for example, in chemical plants, refineries, tank farms, vehicles, sewage treatment plants, airports, grain mills or seaports.
